Description

Technical Field

[0001] The present invention relates to the technical field of watches, and in particular to a smart watch capable of monitoring water pressure. Background Art

[0002] A watch that monitors water pressure is a smart wearable device. In addition to the basic time display function, it can also detect the water pressure of the watch's environment. This is very practical for some water sports enthusiasts, divers or people engaged in underwater operations. For example, divers can understand their diving depth through the water pressure information displayed on the watch.

[0003] Watches that monitor water pressure contain pressure sensors for sensing water pressure. When the watch comes into contact with water, the water pressure acts on the sensor. The strain gauge inside the sensor will deform due to the pressure change, causing its resistance to change. This resistance change is converted into an electrical signal through a Wheatstone bridge circuit. After signal processing such as amplification, filtering, and analog-to-digital conversion (A / D conversion), the water pressure signal can be converted into data that the watch can recognize and process.

[0004] Existing watches that monitor water pressure are greatly affected by environmental factors. For example, when the water flow is turbulent or there are whirlpools, the dynamic pressure of the water will interfere with the measurement of the watch, making the displayed water pressure value unstable or inaccurate. For example, in environments such as rivers and waterfalls, the water pressure value measured by the watch may fluctuate greatly. The reason is that the water flows quickly, which has a large and unstable impact on the built-in pressure sensor. Summary of the invention

[0005] The purpose of the present invention is to provide a smart watch capable of monitoring water pressure and to reduce the flow of water near a pressure sensor for monitoring water pressure.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0015] Among them, a plurality of protrusions and depressions are arranged on the inner wall of the flow hole to make the inner wall of the flow hole rough. When water flows through, it rubs against the inner wall of the flow hole, and part of the kinetic energy of the water is converted into heat. The water flows through multiple flow holes and converges at one place, impacting and colliding with each other.

[0016] Preferably, it also includes:

[0017] The screen assembly is fixedly connected to the watch case;

[0018] A bottom cover, fixedly connected to the watch case;

[0019] A battery, disposed on the bottom cover and electrically connected to the mainboard, to provide electrical energy;

[0020] Among them, the components displaying numbers in the screen assembly are electrically connected to the mainboard.

[0021] Preferably, curved grooves are provided on both sides of the flow hole in the cover, both ends of the curved grooves are connected to the flow hole, and the curved grooves on both sides of the flow hole are staggered to form a bifurcation in the flow hole.

[0022] Preferably, two symmetrically arranged arc plates are provided on the outer ring of the cover, and the two arc plates are fixedly connected via a plurality of arc blocks, and the arc blocks are fixedly connected to the filter screen, and the filter screen can completely cover the port of the flow hole.

[0024] Preferably, a pressure hole is opened on the cover, and a circular bulging rubber sleeve is fixedly set on the outer ring of the cover. The rubber sleeve has a rebound function and completely covers the pressure hole. By pressing the bulging part of the rubber sleeve, pressure is applied to the water inside the cover, causing the water to flow outward through the flow hole.

[0025] Compared with the prior art, the present invention has the following beneficial effects:

[0026] In the present invention, water flow needs to pass through a flow hole before impacting the pressure sensor. Due to the roughness of the inner wall of the flow hole, the water flow rubs against the inner wall of the flow hole when flowing through, and part of the kinetic energy of the water is converted into heat. In addition, the water flows in through multiple flow holes and converges at one place, impacting and colliding with each other, so that the flow velocity of the water entering the sealing cover is significantly slowed down, thereby weakening the flow of water near the pressure sensor that monitors the water pressure, reducing the impact on the pressure sensor and enhancing stability.

DETAILED DESCRIPTION

[0033] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0034] Reference Figure 1 -Attached Figure 5 , a smart watch capable of monitoring water pressure, comprising:

[0035] Case 1;

[0036] A main board 2 is arranged inside the watch case 1;

[0037] A through hole 3 is provided on the watch case 1;

[0038] The sealing cover 4 is sealed and fixedly connected to the inner wall of the through hole 3, one end of which is in an open state and the other end is in a closed state, and the open end leads to the outside of the watch case 1;

[0039] The pressure sensor 5 is fixedly arranged inside the sealing cover 4, and its connection point passes through the closed end of the sealing cover 4 and is electrically connected to the main board 2;

[0040] The cover 6 is fixedly connected to the sealing cover 4 to block the open end of the sealing cover 4;

[0041] Two flow holes 7 are symmetrically provided on the cover 6, so that water can enter the sealing cover 4 through the flow holes 7 and act on the pressure sensor 5;

[0042] Among them, the inner wall of the flow hole 7 is provided with multiple protrusions and depressions, making the inner wall of the flow hole 7 rough. When water flows through, it rubs against the inner wall of the flow hole 7, and part of the kinetic energy of the water is converted into heat. The water flows through multiple flow holes 7 and converges at one place, impacting and colliding with each other.

[0043] Through the above technical scheme, water flow needs to pass through the flow hole 7 before impacting the pressure sensor 5. Due to the roughness of the inner wall of the flow hole 7, the water flow rubs against the inner wall of the flow hole 7 when flowing through, and part of the kinetic energy of the water is converted into heat. In addition, the water flows into one place through multiple flow holes 7, and impacts and collides with each other, so that the flow velocity of the water entering the sealing cover 4 is significantly slowed down, thereby weakening the flow of water near the pressure sensor 5 that monitors the water pressure, reducing the impact on the pressure sensor 5 and enhancing stability.

[0044] Other smartwatches that can monitor water pressure include:

[0045] The screen assembly 10 is fixedly connected to the watch case 1;

[0046] A bottom cover 11 is fixedly connected to the watch case 1;

[0047] A battery 12 is disposed on the bottom cover 11 and electrically connected to the mainboard 2 to provide electrical energy;

[0048] The digital display components in the screen assembly 10 are electrically connected to the mainboard 2 .

[0049] Bending grooves 13 are provided on both sides of the flow hole 7 in the cover 6, and both ends of the bending grooves 13 are connected to the flow hole 7. The bending grooves 13 on both sides of the flow hole 7 are staggered to form a bifurcation in the flow hole 7. Water flows in from one end of the flow hole 7, and part of the water flows through the bifurcation and flows back into the bending grooves 13, colliding head-on with the water flow in the flow hole 7. The force after the collision serves to reduce the flow velocity of the water.

[0050] Since the water contains impurities, it is easy to block the small-diameter flow hole 7, so the following improvements are made:

[0051] Two symmetrically arranged arc plates 14 are arranged on the outer circle of the cover 6. The two arc plates 14 are fixedly connected by a plurality of arc blocks 15. The arc blocks 15 are fixedly connected to the filter screen 21. The filter screen 21 can completely cover the port of the flow hole 7 to prevent impurities from entering the flow hole 7.

[0052] Two fixing rings 16 are fixedly sleeved on the outer ring of the cover 6, and the outer ring of the fixing ring 16 is lower than the outer ring of the arc plate 14. The two fixing rings 16 are respectively arranged on both sides of the arc plate 14 and abut against the two sides of the arc plate 14. The arc plate 14 is fixedly connected with two magnetic rings 17. The fixing ring 16 has a ring groove 18 adapted to the magnetic ring 17, and the magnetic ring 17 is stuck in the ring groove 18. The fixing ring 16 is magnetic, and the fixing ring 16 and the magnetic ring 17 are magnetically attracted to each other. The area of ​​the filter screen 21 covering the flow hole 7 can be adjusted by rotating the arc plate 14, and the area of ​​the filter screen 21 with attached impurities can be transferred to keep the flow hole 7 unobstructed.

[0053] A pressure hole 19 is provided on the cover 6, and a circular bulging rubber sleeve 20 is fixedly provided on the outer ring of the cover 6. The rubber sleeve 20 has a rebound function and completely covers the pressure hole 19. By pressing the bulging part of the rubber sleeve 20, pressure is applied to the water inside the cover 6, so that the water is prompted to flow outward through the flow hole 7. After passing through the curved groove 13, the water flow will be diverted and re-aggregated, and move unimpeded toward the outside of the watch case 1. Due to the effect of the flow pressure, the water flow rate is faster, which plays an accelerating role and can reversely flush the impurities attached to the filter screen 21.

[0054] Working principle:

[0055] Monitor the water pressure underwater, rotate the arc plate 14 so that the arc plate 14 does not block the flow hole 7, the water flows into the sealing cover 4, and the pressure sensor 5 monitors the water pressure;

[0056] If impurities are found attached to the filter screen 21, the arc plate 14 is rotated so that the area of ​​the filter screen 21 where the impurities are attached is away from the flow hole 7 to keep the flow hole 7 unobstructed;

[0057] When impurities are found attached to the filter 21, the rubber sleeve 20 is pressed to apply pressure to the water inside the cover 6, causing the water to flow outward through the flow hole 7. The water flow will be diverted and re-aggregated after passing through the curved groove 13, and move unimpeded toward the outside of the watch case 1. Due to the flow pressure, the water flow rate is faster, which plays an accelerating role and can reversely flush the impurities attached to the filter 21.

[0058] It should be noted that:

[0059] The mainboard 2 in the watch contains a microprocessor for receiving and processing the electrical signal sent by the pressure sensor 5 and converting it into a water pressure value. Of course, the mainboard 2 may also contain other functions and effects of existing underwater smart watches, which will not be described in detail here;

[0060] Attached Figure 5 It shows the flow direction of water flowing into the flow hole 7.

[0061] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
