Description

Technical Field

[0001] The utility model relates to the technical field of hydrotherapy equipment, in particular to a water flow massage device. Background Art

[0002] Water massage beds, whirlpool bubble baths, integrated hydrotherapy pools and other products are usually equipped with a water flow massage device, which includes a number of massage nozzles for water massage. The pressure of the water massage (i.e., the massage strength) can be set by adjusting the water flow intensity. The ideal state is that the pressure fluctuation of the water massage is small when the number of massage nozzles opened changes.

[0003] The existing technology generally does not regulate the spray intensity of the massage nozzles, nor does it maintain constant pressure, and cannot adapt to a wide range of people. Since the spray intensity of the massage nozzles is not adjustable, when all the massage nozzles are fully open, the massage intensity cannot be adjusted to a lower level.

[0004] Increasing massage intensity with existing technology typically requires shutting off a certain number of massage nozzles. If a single-user device has multiple massage nozzles, shutting off other nozzles when only a localized massage is needed can cause a sharp increase in the spray intensity of a single nozzle or group of nozzles, potentially causing injury or discomfort. If multiple devices share a single system, increasing massage intensity requires shutting off the nozzles of others, impacting their use. If most massage nozzles are shut off, the remaining nozzles can experience a sharp increase in spray intensity, similarly leading to injury or discomfort.

[0005] In order to avoid mutual interference, some usage scenarios adopt the method of one person and one water pump. The overall cost of this method is too high, and the probability of failure will also increase if there are too many water pumps.

[0006] The information disclosed in this background technology section is only intended to deepen the understanding of the overall background technology of the present invention, and should not be regarded as an admission or any form of suggestion that the information constitutes the prior art already known to those skilled in the art. Utility Model Content

[0007] In response to the defects in the prior art, the purpose of the present utility model is to provide a water flow massage device, in which the spray force of the massage nozzle is adjustable, the massage force fluctuates less when the number of massage nozzles opened changes, the water pressure can be set manually, and it can adapt to people with different stimulation intensity tolerance, including infants, young adults, the elderly, etc. The massage force is adjustable, the accuracy is good, and it is easy to operate.

[0008] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0009] A water flow massage device, characterized by comprising:

[0010] The massage pool body 1 is provided with a plurality of massage nozzles on the inner wall of the pool body;

[0011] The magnetic sensors are provided in a one-to-one correspondence with the massage nozzles and are used to detect the on / off status of each massage nozzle by means of magnetic sensing;

[0012] A controller 5 is electrically connected to the magnetic sensor and is used to obtain a nozzle switch signal;

[0013] The frequency converter 4 is electrically connected to the controller 5 and is used to obtain a first frequency fine-tuning signal;

[0014] The water pump 3 is electrically connected to the frequency converter 4 and is used to obtain a water outlet speed adjustment signal.

[0015] On the basis of the above technical solutions, it also includes:

[0016] Water pressure sensor 2, which is set in one-to-one correspondence with the massage nozzles and is used to detect the water pressure of each massage nozzle;

[0017] The controller 5 is electrically connected to the water pressure sensor 2 and is used to obtain the outlet water pressure signal;

[0018] The frequency converter 4 is electrically connected to the controller 5 and is used to obtain the second frequency fine-tuning signal.

[0019] On the basis of the above technical solutions, it also includes:

[0020] Manual button or other setting interface for setting the intensity of massage;

[0021] The controller 5 is electrically connected to the manual button or other setting interface, and is used to obtain a massage intensity selection signal;

[0023] On the basis of the above technical solution, a magnetic component is provided in the valve core of the massage nozzle, and the magnetic component is adapted to the magnetic sensor.

[0024] On the basis of the above technical solution, the nozzle switch signal is fed back to the controller 5 in real time. The controller 5 adjusts the speed of the water pump through the inverter 4 to change the water outlet speed to match the number of different massage nozzles opened, so that the spray force of the massage nozzle is constant within the preset range, thereby obtaining a stable massage force.

[0025] On the basis of the above technical solution, the outlet water pressure signal is fed back to the controller 5 in real time. The controller 5 adjusts the speed of the water pump through the inverter 4 to change the water outlet speed to match the number of different massage nozzles opened, so that the outlet water pressure is constant within the preset range, thereby obtaining a stable massage intensity.

[0026] On the basis of the above technical solution, the massage intensity selection signal is fed back to the controller 5 in real time, and the controller 5 sends the inverter peak frequency adjustment signal to the inverter 4. Different massage intensity selection signals correspond to different inverter peak frequency adjustment signals.

[0027] On the basis of the above technical solution, when the outlet water pressure collected by the water pressure sensor 2 fluctuates, the frequency converter 4 first executes the first frequency fine-tuning signal and then executes the second frequency fine-tuning signal.

[0028] The water flow massage device described in the utility model has the following beneficial effects:

[0029] 1. Using magnetic sensing, the on / off status of the massage nozzles is detected one by one; the detection is more accurate and can ensure that the water pressure remains constant within the preset range when the water pressure fluctuates;

[0030] 2. Use water pressure sensors to detect the water pressure of massage nozzles one by one; the detection is more accurate and safer, which can improve the automation level of the device and provide users with a better experience;

[0031] 3. The collected signals are linked to the controller to send frequency fine-tuning signals to the inverter in real time; the response is fast, the operation stability is improved, and the user experience is better;

[0032] 4. The inverter adjusts the output frequency based on the second frequency fine-tuning signal (water outlet pressure), the first frequency fine-tuning signal (number of nozzles opened) and the selected pressure (manual setting), to more accurately ensure that the water pressure is constant within the preset range.

[0033] The utility model discloses a water flow massage device, which can adjust the water flow pressure in stages. The spray intensity of the massage nozzles fluctuates less with the number of nozzles opened. When a single person only needs to massage a part of the body, the device will not generate an excessively strong water flow. A single water pump is used to save installation and maintenance costs.

[0037] The present invention will be described in further detail below with reference to the accompanying drawings. The detailed description, which is provided in conjunction with exemplary embodiments of the present invention and includes various details of the embodiments to aid understanding, should be considered merely exemplary. Therefore, those skilled in the art will recognize that various changes and modifications may be made to the embodiments described herein without departing from the scope and spirit of the present invention. Similarly, for the sake of clarity and conciseness, descriptions of well-known functions and structures are omitted from the following description.

[0038] like Figure 1 As shown, the utility model provides a water flow massage device, comprising:

[0039] The massage pool body 1 is provided with a plurality of massage nozzles on the inner wall of the pool body; the number and position of the massage nozzles are set according to the massage needs and are not specifically limited;

[0040] The magnetic sensors are provided in a one-to-one correspondence with the massage nozzles and are used to detect the on / off status of each massage nozzle by means of magnetic sensing;

[0041] A controller 5 is electrically connected to the magnetic sensor and is used to obtain a nozzle switch signal;

[0042] The frequency converter 4 is electrically connected to the controller 5 and is used to obtain a first frequency fine-tuning signal;

[0043] The water pump 3 is electrically connected to the frequency converter 4 and is used to obtain a water outlet speed adjustment signal.

[0044] The magnetic sensor detects the switching status of each massage nozzle to form a corresponding nozzle switching signal, and the nozzle switching signal is fed back to the controller 5 in real time. The controller 5 generates a first frequency fine-tuning signal corresponding to the nozzle switching signal. The controller 5 sends the first frequency fine-tuning signal to the inverter 4. The inverter 4 generates a water outlet speed adjustment signal corresponding to the first frequency fine-tuning signal. The inverter 4 sends the water outlet speed adjustment signal to the water pump 3 to adjust its speed. The water outlet speed is changed by changing the speed of the water pump 3 to match the number of different massage nozzles opened, so that the spray force of the massage nozzle is constant within a preset range, thereby obtaining a stable massage force.

[0045] On the basis of the above technical solutions, it also includes:

[0046] Water pressure sensor 2, which is set in one-to-one correspondence with the massage nozzles and is used to detect the water pressure of each massage nozzle;

[0047] The controller 5 is electrically connected to the water pressure sensor 2 and is used to obtain the outlet water pressure signal;

[0048] The frequency converter 4 is electrically connected to the controller 5 and is used to obtain the second frequency fine-tuning signal.

[0049] The water pressure sensor 2 detects the water pressure of each massage nozzle to form a corresponding water pressure signal. The water pressure signal is fed back to the controller 5 in real time. The controller 5 generates a second frequency fine-tuning signal corresponding to the water pressure signal. The controller 5 sends the second frequency fine-tuning signal to the frequency converter 4. The frequency converter 4 generates a water speed adjustment signal corresponding to the second frequency fine-tuning signal. The frequency converter 4 sends the water speed adjustment signal to the water pump 3 to adjust its speed. The water speed is changed by changing the speed of the water pump 3 to match the number of different massage nozzles opened, so that the water pressure is constant within a preset range, thereby obtaining a stable massage intensity.

[0050] In addition to the one-to-one correspondence between the water pressure sensor 2 and the massage nozzle, several massage nozzles can be connected to the same main pipe through branch pipes. Setting the water pressure sensor 2 in the main pipe can save the number of sensors used and ensure the unified measurement of the massage water pressure in the same part. A solenoid valve can also be set in the main pipe to achieve unified adjustment of the massage water pressure in the same part.

[0051] On the basis of the above technical solutions, it also includes:

[0052] Manual button or other setting interface for setting the intensity of massage;

[0053] The controller 5 is electrically connected to the manual button or other setting interface, and is used to obtain a massage intensity selection signal;

[0054] The frequency converter 4 is electrically connected to the controller 5 and is used to obtain a third frequency fine-tuning signal.

[0055] A massage force selection signal is generated through a manual button or other setting interface. The massage force selection signal corresponds to the massage force set by the user. The massage force selection signal is fed back to the controller 5 in real time. The controller 5 generates a third frequency fine-tuning signal corresponding to the massage force selection signal. The third frequency fine-tuning signal corresponds to the inverter peak frequency adjustment signal. Different massage force selection signals correspond to different inverter peak frequency adjustment signals. The controller 5 sends the inverter peak frequency adjustment signal to the inverter 4. The inverter 4 generates a water outlet speed adjustment signal corresponding to the inverter peak frequency adjustment signal.

[0056] The inverter peak frequency adjustment signal adopts a preset value, which serves as both a protection measure and an initial preset position for the inverter operation.

[0057] The other setting interface may be a touch screen or an encoder switch (rotating to select different gears).

[0058] On the basis of the above technical solution, a magnetic component is provided in the valve core of the massage nozzle, and the magnetic component is adapted to the magnetic sensor.

[0059] The magnetic sensor detects the switch status of each massage nozzle by detecting the position change of the magnetic component.

[0060] On the basis of the above technical solution, when the outlet water pressure collected by the water pressure sensor 2 fluctuates, the frequency converter 4 first executes the first frequency fine-tuning signal and then executes the second frequency fine-tuning signal.

[0061] Due to the influence of the sudden closure of the massage nozzle, the water pressure of water pressure sensor 2 fluctuates and the pressure value is inaccurate for a short time. At this time, the frequency converter first executes the first frequency fine-tuning signal to match the number of massage nozzles opened, and then executes the second frequency fine-tuning signal to perform pressure ratio fine-tuning.

[0062] By adopting the above technical solution, when a single-person device has multiple massage nozzles distributed, when only a local massage impact is required, the remaining massage nozzles can be closed at will without increasing the spray force of the massage nozzle that needs to be used.

[0063] By adopting the above technical solution, the massage nozzles of multi-person equipment share a common system. When the massage nozzles of most massage positions are turned off, the spray strength of the massage nozzles that need to be used will not be affected.

[0064] Based on the fact that there is no need to consider the situations where impact injuries will not be caused when at least one nozzle is opened and the force is too strong to be suitable, the power of the massage pump can be increased. When all the massage nozzles are opened, a stronger jet stimulation force than the conventional massage nozzle can still be obtained.
