Description

Technical Field

[0001] The invention relates to the technical field of smart water meters, in particular to a smart water meter which does not leak or leak water. Background Art

[0002] Smart water meter is an intelligent metering instrument used to measure and record water consumption in a single water flow channel. It can automatically collect water flow information and transmit water consumption data to the water supply management system or user terminal through the built-in microprocessor and communication module, thus realizing accurate water measurement and intelligent management.

[0003] At present, traditional smart water meters generally only have the functions of measuring water consumption and remote control, and are unable to identify and control water leakage and dripping, which makes the use of smart water meters have certain limitations. For this reason, we propose a smart water meter that does not leak or leak. Summary of the invention

[0004] The purpose of the present invention is to provide a smart water meter without dripping or water leakage, so as to solve the problems raised in the above-mentioned background technology.

[0005] To achieve the above object, the present invention provides the following technical solution: a smart water meter without dripping or water leakage comprises:

[0006] A water meter body and a main control part; a water inlet pipe and a water outlet pipe are arranged at the front and rear ends of the water meter body, and a controllable valve for flow control is arranged inside the water meter body; a pressure transmitter for identifying the pressure inside the water meter body and a meter core for identifying the water flow rate are installed inside the water meter body.

[0007] The pressure transmitter and the meter core are both adapted and connected to the main control part. When the faucet or pipe is leaking, the pressure in the water meter body slowly decreases. When the pressure is lower than the preset threshold value one, the main control part controls the controllable valve to open and add water. When the pressure in the water meter body is higher than the preset threshold value two, a delay of n seconds is performed. If no new water flow is detected within n seconds, the controllable valve is closed. If water flows, the water flow stops for n seconds and then re-detected. After three consecutive times, when the pressure in the water meter body drops to the preset threshold value one, it is determined to be a pipe leak or a user intentionally stealing water, and an alarm message is sent and the controllable valve is closed.

[0008] When the continuous flow reaches the set flow value, it is temporarily determined that the user's home is leaking water, and the controllable valve is closed for the first time. After the valve is closed for m seconds, the alarm is automatically released, and the user can still use water. When the continuous water use exceeds the set value again, the controllable valve is closed again and an alarm is sounded. This is repeated three times in a row, and it is determined to be leaking water. The controllable valve is completely closed to avoid leaking water, and a water leak alarm message is sent to the user's mobile phone. After confirming that the water is manually released or has returned to normal, the valve is released, thereby forming a water leak alarm function to reduce the risk of water waste;

[0009] A main control part is arranged inside the water meter body, and the pressure transmitter, the meter core and the controllable valve are electrically connected to the main control part.

[0010] An alarm for abnormal alarm of water leakage and dripping detection is installed on the outer side of the water meter body, and the alarm is electrically connected to the main control part.

[0011] The water meter body includes an installation box which is installed on the water inlet pipe. Two groups of symmetrically arranged partitions are fixed inside the installation box. The interior of the installation box forms two groups of first operating chambers and one group of second operating chambers under the dividing effect of the two groups of partitions. The second operating chamber is located between the two groups of first operating chambers. The second operating chamber is connected to the interior of the water inlet pipe. A processing component for puncturing bubbles in convective water is arranged between the installation box and the water inlet pipe.

[0012] The processing component includes a strip plate arranged between the installation box and the water inlet pipe, and multiple groups of puncture needles for auxiliary puncture are fixed to the lower end of the strip plate. The interior of the first operating cavity is provided with a connecting component for connecting the strip plate and an extrusion component for extruding the strip plate.

[0013] The connecting assembly includes multiple groups of connecting rods slidably connected to the installation box, one end of each group of connecting rods is fixed to the upper end of the strip plate, a transmission plate is provided inside the first operating cavity, one end of each group of connecting rods is located inside the first operating cavity and fixed to the transmission plate, and a first spring is sleeved on the outer side of each group of connecting rods.

[0014] The extrusion assembly includes a rotating rod rotatably connected to the inside of the first operating chamber, a driving disk is fixed on the rotating rod, and a plurality of groups of protrusions for resisting and transmitting the transmission plate are fixed on the outer side of the driving disk in a circular array. A rotating assembly for rotating the rotating rod is arranged inside the second operating chamber.

[0015] The rotating assembly includes a rotating shaft rotatably connected to the second operating chamber, the two ends of the rotating shaft are respectively fixed to one end of the rotating rods inside the two groups of first operating chambers, and the rotating shaft is fixed with transmission blades for resisting the circulating water.

[0016] The method for using the above-mentioned smart water meter without dripping or leakage comprises the following steps:

[0017] S1: When using the smart water meter that does not drip or leak, the water inlet pipe and the water outlet pipe at the front and rear ends of the water meter body are respectively installed and connected with the corresponding pipes through threads. After the installation and connection are completed, the controllable valve inside the water meter body is opened to allow water to flow through the water meter body;

[0018] S2: During the process of water circulation and transportation in the water meter body, the flow rate of the circulating water is monitored through the meter core. When the continuous flow rate reaches the specified flow value, the flow of the pipeline is closed through the controllable valve to prevent water leakage;

[0019] S3: After the continuous water flow rate monitored by the meter core reaches the set value, the alarm is activated through the main control part, so that the alarm sounds an alarm, and the information of water leakage is transmitted in time through the alarm function;

[0020] S4: When the smart water meter without dripping or leakage is used, when the faucet or pipe leaks, the pressure in the water meter body will slowly decrease. When the pressure is lower than the preset threshold, the main control part controls the controllable valve to open and add water.

[0021] S5: When the pressure inside the water meter body is higher than the preset threshold value 2, a delay of n seconds is performed. If no new water flow is detected within n seconds, the controllable valve is closed. If water is flowing, the water flow stops for n seconds and then re-detected. After three consecutive times, if the pressure inside the water meter body is lower than the preset threshold value 1, it is determined to be a pipe leakage or intentional water theft by the user, an alarm message is sent, and the controllable valve is closed, so as to identify the pipe leakage at the back end of the smart water meter and perform an alarm operation;

[0022] S6: During the process of water being transported inside the water inlet pipe, the circulating water and the transmission blades inside the installation box counteract each other to drive the rotating shaft to rotate on the installation box. During the process of the rotating shaft rotating, the rotating rod is driven to rotate. During the process of the rotating rod rotating, the driving disk is driven to rotate.

[0023] S7: During the rotation of the driving disk, each group of protrusions on the driving disk is pressed against the transmission plate in turn. During the pressing of the protrusions against the transmission plate, the transmission plate, the connecting rod and the strip plate are pushed to move under force. During the period when the protrusions are not pressed against the transmission plate, the transmission plate, the connecting rod and the strip plate are reset by the elastic force of the first spring. Therefore, during the rotation of the rotating rod and the driving disk, the transmission plate, the connecting rod and the strip plate are pressed to move up and down through transmission. During the reciprocating motion of the strip plate, each group of puncture needles is driven to reciprocate up and down synchronously. Through the reciprocating motion of each group of puncture needles, the bubbles in the circulated water are punctured and removed. By removing the bubbles, the smart water meter without dripping or water leakage can be operated more accurately.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] 1. During the use of the non-drip and non-leakage smart water meter of the present invention, the main control part, the meter core and the pressure transmitter cooperate with each other to identify and judge the leakage and dripping of the non-drip and non-leakage smart water meter, so that the non-drip and non-leakage smart water meter is more intelligent and the measurement is more accurate during use.

[0026] 2. During use of the non-drip and non-leakage smart water meter of the present invention, bubbles existing in the circulating water are punctured and removed through the cooperation of components such as processing components. By removing the bubbles, the non-drip and non-leakage smart water meter can be operated and used more accurately. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0038] Example 1

[0039] See also Figure 1-Figure 6 The non-drip and non-leakage smart water meter shown in the figure includes a water meter body 101 and a main control part; a water inlet pipe 102 and a water outlet pipe 103 are arranged at the front and rear ends of the water meter body 101, and a controllable valve 104 for flow control is arranged inside the water meter body 101; a pressure transmitter 2 for identifying the pressure inside the water meter body 101 and a meter core 3 for identifying the water flow rate are installed inside the water meter body 101;

[0040] It should be noted here that: through the mutual cooperation of the main control part, the meter core 3 and the pressure transmitter 2, the leakage and dripping of the smart water meter without dripping or leakage can be identified and judged, making the smart water meter without dripping or leakage more intelligent during use.

[0041] The pressure transmitter 2 and the meter core 3 are both connected to the main control part. The normal water use process of the user is that the user turns on the faucet, the pressure in the water inlet pipe slowly decreases, the main control part controls the controllable valve 104 to open, water flows out normally, and the meter core charges normally.

[0042] When the faucet or pipe is leaking, the pressure in the water meter body 101 will slowly decrease. When the pressure is lower than the preset threshold value 1, the main control part controls the controllable valve 104 to open and add water. When the pressure in the water meter body 101 is higher than the preset threshold value 2, it will delay for n seconds. If no new water flow is detected within n seconds, the controllable valve 104 will be closed. If water is flowing, the water flow will be stopped for n seconds and then re-detected. If it is repeated three times, the water addition will be stopped. When the pressure in the water meter body 101 is lower than the preset threshold value 1, it is determined to be a pipe leak or the user is intentionally stealing water, and an alarm message will be sent and the controllable valve 104 will be closed.

[0043] When the continuous flow reaches the set flow value, it is temporarily determined that the user's home is leaking water, and the controllable valve 104 is closed for the first time. After the valve is closed for m seconds, the alarm is automatically released, and the user can still use water. When the continuous water use exceeds the set value again, the controllable valve 104 is closed again and an alarm is sounded. This is repeated three times in a row, and it is determined that there is a water leak. The controllable valve 104 is completely closed to avoid water leaks, and a water leak alarm message is sent to the user's mobile phone. After confirming that the water is manually released or has returned to normal, the valve is released, thereby forming a water leak alarm function to reduce the risk of water waste;

[0044] Specifically, during the use of the smart water meter that does not drip or leak, when the faucet or pipe drips, the pressure in the water meter body 101 will slowly decrease. When the pressure in the water meter body 101 is lower than 0.053MPa (in this embodiment, the preset threshold value 1 is 0.053MPa), the main control part controls the controllable valve 104 to open and add water. When the pressure in the water meter body 101 is higher than 0.1MPa (in this embodiment, the preset threshold value 2 is 0.1MPa), it is delayed for 5 seconds to detect whether new water flows through within 5 seconds (i.e., whether the meter core is metered). If water flows through (at this time, it is determined that the user uses water normally), the water flow stops for 5 seconds and then re-detected. If no water flows through (the meter core is not metered), the controllable valve 104 is closed, and the above actions are repeated. The pressure in the water meter body is slowly reduced to below 0.053MPa for three consecutive times, and the meter core is not metered, it is determined that the pipeline is leaking or the user is intentionally stealing water, and an alarm message is sent and the controllable valve 104 is completely closed (the user is prohibited from using water).

[0045] The water meter body 101 is provided with a main control part inside, and the pressure transmitter 2, the meter core 3 and the controllable valve 104 are electrically connected to the main control part; an alarm for abnormal alarm of water leakage and dripping detection is installed on the outside of the water meter body 101, and the alarm is electrically connected to the main control part;

[0046] It should be noted here that during the use of the smart water meter that does not drip or leak, the flow of the circulating water is monitored through the meter core 3. When the continuous flow reaches the set flow value, the circulation of the pipeline is closed through the controllable valve 104 to avoid water leakage caused by pipeline damage or the faucet in the user's home is not closed, and a water leakage alarm message is sent to the user's mobile phone. Specifically, the upper limit of a single continuous water consumption is set to 200L. When the continuous water consumption measured by the meter core reaches 200L, it is temporarily determined that the user's home is leaking, and the controllable valve 104 is closed for the first time. After 60 seconds of closing the valve, the alarm is automatically released, and the user can still use water. When the continuous water consumption exceeds 200L again, the controllable valve 104 is closed again and an alarm is sounded. This is repeated three times in a row, and it is determined to be a water leakage. The controllable valve 104 is completely closed to avoid water leakage caused by pipeline damage or the faucet in the user's home is not closed. A water leakage alarm message is sent to the user's mobile phone. After confirming that it is artificial water discharge or has returned to normal, the closure is released, thereby forming a water leakage alarm function and reducing the risk of water waste.

[0047] The controllable valve 104 includes an electric drive valve, a gas drive valve, and a hydraulic drive valve. The electric drive valve can be a solenoid valve or an electric valve. In this embodiment, in order to be suitable for civilian use, the controllable valve 104 is a solenoid valve, and the specific model belongs to the prior art and will not be described here.

[0048] In this embodiment, the main control part is a single-chip microcomputer and a peripheral circuit for driving the single-chip microcomputer. The specific structure and model belong to the prior art and will not be described here.

[0049] In this embodiment, the movement 3 can be a volumetric movement, a speed movement or any movement in the prior art. The specific structure to be adopted belongs to the prior art and will not be described in detail here.

[0050] Example 2

[0051] See also Figure 7-Figure 9 The water meter body 101 includes an installation box 4 which is installed on the water inlet pipe 102. Two groups of symmetrically arranged partitions 5 are fixed inside the installation box 4. The interior of the installation box 4 forms two groups of first operating chambers 401 and one group of second operating chambers 402 under the dividing effect of the two groups of partitions 5. The second operating chamber 402 is located between the two groups of first operating chambers 401. The second operating chamber 402 is connected to the interior of the water inlet pipe 102. A processing component for puncturing bubbles in convective water is arranged between the installation box 4 and the water inlet pipe 102.

[0052] The processing assembly includes a strip plate 601 disposed between the installation box 4 and the water inlet pipe 102, and a plurality of puncture needles 602 for assisting puncture are fixed at the lower end of the strip plate 601. A connecting assembly for connecting the strip plate 601 and an extrusion assembly for extruding the strip plate 601 are disposed inside the first operating chamber 401;

[0053] It should be noted here that: through transmission, the transmission plate 702, the connecting rod 701 and the strip plate 601 are forced to move up and down reciprocatingly. During the reciprocating motion of the strip plate 601, each group of puncture needles 602 is driven to move up and down synchronously. Through the reciprocating motion of each group of puncture needles 602, the bubbles existing in the circulating water are punctured and removed. By removing the bubbles, the smart water meter without dripping or water leakage can be operated more accurately.

[0054] The connecting assembly includes a plurality of connecting rods 701 slidably connected to the installation box 4, one end of each connecting rod 701 is fixed to the upper end of the strip plate 601, a transmission plate 702 is arranged inside the first operating chamber 401, one end of each connecting rod 701 is located inside the first operating chamber 401 and is fixed to the transmission plate 702, and a first spring 703 is sleeved on the outer side of each connecting rod 701; the extrusion assembly includes a rotating rod 901 rotatably connected to the inside of the first operating chamber 401, a driving disk 902 is fixed on the rotating rod 901, and a plurality of protrusions 903 for resisting and transmitting the transmission plate 702 are fixed on the outer side of the driving disk 902 in a state of an annular array, and a rotating assembly for rotating the rotating rod 901 is arranged inside the second operating chamber 402;

[0055] It should be noted here that: the rotating rod 901 is driven to rotate by the rotating assembly, and during the rotation of the rotating rod 901, the driving disk 902 is driven to rotate, and during the rotation of the driving disk 902, each group of protrusions 903 on the driving disk 902 is sequentially abutted against the transmission plate 702, and during the abutment between the protrusions 903 and the transmission plate 702, the transmission plate 702, the connecting rod 701 and the strip plate 601 are pushed to move, and during the process when the protrusions 903 are not abutted against the transmission plate 702, the transmission plate 702, the connecting rod 701 and the strip plate 601 are reset by the elastic force of the first spring 703, so that during the rotation of the rotating rod 901 and the driving disk 902, the transmission plate 702, the connecting rod 701 and the strip plate 601 are forced to reciprocate up and down through transmission;

[0056] The rotating assembly includes a rotating shaft 1001 rotatably connected to the second operating chamber 402, and both ends of the rotating shaft 1001 are respectively fixed to one end of the rotating rod 901 inside the two sets of first operating chambers 401, and a transmission blade 1002 for resisting the circulating water is fixed on the rotating shaft 1001;

[0057] It should be noted here that during the transportation of water inside the water inlet pipe 102, the circulating water and the transmission blades 1002 inside the installation box 4 counteract each other, driving the rotating shaft 1001 to rotate on the installation box 4. During the rotation of the rotating shaft 1001, the rotating rod 901 is driven to rotate.

[0058] The method for using a smart water meter without dripping or leakage includes the following steps:

[0059] S1: During the use of the smart water meter without dripping or leakage, the water inlet pipe 102 and the water outlet pipe 103 at the front and rear ends of the water meter body 101 are respectively installed and connected with the corresponding pipes by means of threads. After the installation and connection are completed, the controllable valve 104 inside the water meter body 101 is opened to allow water to flow and transport normally;

[0060] S2: During the process of water circulation and transportation in the water meter body 101, the flow rate of the circulating and transported water is monitored through the meter core 3. When the continuous flow rate reaches the set flow rate value, it is temporarily determined that the user's home is leaking water, and the controllable valve 104 is closed for the first time. After the valve is closed for m seconds, the alarm is automatically released, and the user can still use water. When the continuous water consumption exceeds the set value again, the controllable valve 104 is closed again and an alarm is sounded. This is repeated three times in a row, and it is determined that there is a water leak. The controllable valve 104 is completely closed to avoid water leaks caused by damaged pipes or the faucets in the user's home are not closed, and a water leak alarm message is sent to the user's mobile phone. After confirming that the water is manually released or has returned to normal, the valve is released, thereby forming a water leak alarm function to reduce the risk of water waste;

[0061] For example, if the flow protection value set by the water meter is 200L, when the continuous water consumption exceeds 200L, it is temporarily determined that the user's home is leaking water, and the controllable valve 104 is closed for the first time. After 60 seconds of closing the valve, the alarm is automatically released, and the user can still use water. When the continuous water consumption exceeds 200L again, the controllable valve 104 is closed again and an alarm is sounded. This is repeated three times in a row, and it is determined that there is a water leak. The controllable valve 104 is completely closed, and an alarm message is sent to the user's mobile phone. After confirming that the water is manually released or has returned to normal, the closure is released, thereby forming a water leak alarm function, reducing the risk of water waste caused by pipe damage or when the faucet in the user's home is not closed;

[0062] S3: After the continuous flow of water monitored by the meter core 3 reaches a specified value, the alarm is activated through the main control part, so that the alarm sounds an alarm, and the information of water leakage is transmitted in time through the alarm;

[0063] S4: During the use of the smart water meter without dripping or leaking, when the faucet or pipe leaks, the pressure in the water meter body 101 will slowly decrease. When the pressure is lower than the preset threshold, the main control part controls the controllable valve 104 to open and add water;

[0064] S5: When the pressure in the water meter body 101 is higher than the preset threshold, a delay of n seconds is performed. If no new water is detected within n seconds, the controllable valve 104 is closed. If water is flowing, the timing is restarted after n seconds. If the pressure in the water meter body 101 decreases slowly for three consecutive times, it is determined to be a pipeline leakage or a user intentionally stealing water. An alarm message is sent and the controllable valve 104 is closed, so as to identify the leakage of the smart water meter and perform an alarm operation.

[0065] Specifically, when the faucet or pipe is leaking, the pressure in the water meter body 101 will slowly decrease. When the pressure in the water meter body 101 is lower than 0.053MPa, the main control part controls the controllable valve 104 to open and add water. When the pressure in the water meter body 101 is higher than 0.1MPa, it will delay for 5 seconds to see if new water is detected within 5 seconds (i.e., whether the meter core is measuring). If water is flowing (it is determined that the user is using water normally at this time), the water flow will be stopped for 5 seconds and then re-detected. If no water is flowing (the meter core is not measuring), the controllable valve 104 will be closed, and the above actions will be repeated three times in a row. For three times in a row, the pressure in the water meter body is reduced to below 0.053MPa, and the meter core is not measuring. It is determined that the pipeline is leaking or the user is intentionally stealing water, and an alarm message is sent and the controllable valve 104 is completely closed (the user is prohibited from using water).

[0066] S6: During the process of water being transported inside the water inlet pipe 102, the circulating water and the transmission blades 1002 inside the installation box 4 counteract each other to drive the rotating shaft 1001 to rotate on the installation box 4. During the rotation of the rotating shaft 1001, the rotating rod 901 is driven to rotate. During the rotation of the rotating rod 901, the driving disk 902 is driven to rotate.

[0067] S7: During the rotation of the driving disk 902, the groups of protrusions 903 on the driving disk 902 are sequentially abutted against the transmission plate 702. During the abutment between the protrusions 903 and the transmission plate 702, the transmission plate 702, the connecting rod 701 and the strip plate 601 are pushed to move. During the non-abutment between the protrusions 903 and the transmission plate 702, the elastic force of the first spring 703 causes the transmission plate 702, the connecting rod 701 and the strip plate 601 to reset. During the rotation of the moving rod 901 and the driving disk 902, the transmission causes the transmission plate 702, the connecting rod 701 and the strip plate 601 to be subjected to force to perform up and down reciprocating motion. During the reciprocating motion of the strip plate 601, each group of puncture needles 602 is driven to synchronously reciprocate up and down. Through the reciprocating motion of each group of puncture needles 602, the bubbles existing in the circulating water are punctured and removed. By removing the bubbles, the smart water meter without dripping or water leakage can be operated more accurately.

10. A method for using a non-drip and non-leakage smart water meter, which refers to the non-drip and non-leakage smart water meter according to any one of claims 1 to 9, characterized in that: The following steps are involved: S1: During the use of the smart water meter that does not drip or leak, the water inlet pipe (102) and the water outlet pipe (103) at the front and rear ends of the water meter body (101) are respectively installed and connected to the corresponding pipes by means of threads. After the installation and connection are completed, the controllable valve (104) inside the water meter body (101) is opened to allow water to circulate and be transported normally; S2: During the process of water flowing through the water meter body (101), the flow rate of the flowing water is monitored through the meter core (3). When the continuous flow rate reaches the set flow rate value, it is temporarily determined that the user's home has a water leak, and the controllable valve (104) is closed for the first time. After the valve is closed for m seconds, the alarm is automatically released and the user can still use water. When the continuous water consumption exceeds the set value again, the controllable valve (104) is closed again and an alarm is sounded. If this is repeated three times in a row, it is determined that there is a water leak, and the controllable valve (104) is completely closed to avoid water leak, and a water leak alarm message is sent to the user's mobile phone; S3: After the continuous flow of water monitored by the meter core (3) reaches the set flow value, the main control part starts the alarm to make the alarm sound, and the information of water leakage is transmitted in time through the alarm function; S4: During the use of the smart water meter that does not drip or leak, when the faucet or pipe leaks, the pressure in the water meter body (101) will slowly decrease. When the pressure is lower than a preset threshold value, the main control part controls the controllable valve (104) to open and add water; S5: When the pressure in the water meter body (101) is higher than the preset threshold value 2, a delay of n seconds is performed. If no new water flow is detected within n seconds, the controllable valve (104) is closed. If water is flowing, the water flow stops for n seconds and then the test is repeated. After three consecutive times, if the pressure in the water meter body (101) is lower than the preset threshold value 1, it is determined that there is a pipeline leak or the user is intentionally stealing water. An alarm message is sent and the controllable valve (104) is closed, thereby identifying the pipeline leak at the back end of the smart water meter and performing an alarm operation. S6: During the process of water being transported inside the water inlet pipe (102), the circulating water and the transmission blades (1002) inside the installation box (4) counteract each other to drive the rotating shaft (1001) to rotate on the installation box (4). During the process of the rotating shaft (1001) rotating, the rotating rod (901) is driven to rotate. During the process of the rotating rod (901) rotating, the driving disc (902) is driven to rotate. S7: When the driving disk (902) rotates, each group of protrusions (903) on the driving disk (902) is pressed against the transmission plate (702) in sequence. When the protrusions (903) are pressed against the transmission plate (702), the transmission plate (702), the connecting rod (701) and the strip plate (601) are pushed to move. When the protrusions (903) are not pressed against the transmission plate (702), the elastic force of the first spring (703) causes the transmission plate (702), the connecting rod (701) and the strip plate (601) to move. Therefore, during the rotation of the rotating rod (901) and the driving disk (902), the transmission plate (702), the connecting rod (701) and the strip plate (601) are forced to move up and down reciprocatingly. During the reciprocating motion of the strip plate (601), each group of puncture needles (602) are driven to move up and down synchronously. Through the reciprocating motion of each group of puncture needles (602), the bubbles existing in the circulating water are punctured and removed. By removing the bubbles, the intelligent water meter without dripping or water leakage can be operated more accurately.
