Description

Technical Field

[0001] The utility model relates to the technical field of water tank water volume monitoring, in particular to a device that uses a pressure sensor to monitor the water volume in a water tank. Background Art

[0002] The coffee machines, instant water dispensers and other similar household appliances on the market currently have strict requirements on the water output of the products. If the water tank has a water volume monitoring function, this situation can be avoided. The existing water tank water volume monitoring generally adopts capacitive sensing intelligent identification, weighing module and pressure sensor to monitor and manage the water volume in the water tank.

[0003] In the prior art, traditional water level monitoring of water tanks usually relies on pressure sensors, which are connected to the water tanks through hoses and cannot directly contact water. In order to accurately measure the water level, the sensor needs to be placed at a position higher than the maximum water level of the water tank. However, this configuration will cause water ingress into the connecting hose over time, thereby rendering the monitoring ineffective. Although the existing pressure sensors for water level monitoring of water tanks allow them to directly contact water, scale will accumulate inside the water tank connector over time, which will affect the accuracy of the pressure sensor. Due to the fixed installation method between the water tank connector and the support base, the scale cannot be cleaned in time, thereby affecting the monitoring accuracy of the sensor and reducing its use effect.

[0004] Therefore, a device that uses a pressure sensor to monitor the water level in a water tank is needed to solve the problem that the existing monitoring device has a relatively fixed water tank connector that cannot be cleaned in time, thereby affecting the accuracy of pressure sensor monitoring.

After completion, reset it and use the sealing ring 5 to insert it into the inner wall of the support seat 2, and keep the middle of the support seat 2 and the sealing ring 5 at the bottom of the water tank 1 plugged in. Then, reset the plug block 6, let one side of it penetrate the connecting groove 8, and insert it into the inner wall of the card slot 9, so that the installation between the support seat 2, the sealing ring 5 and the water tank connector 3 is more stable. When in use, water is poured into the interior of the water tank 1 and injected into the inner wall of the water tank connector 3 through the pipe at the bottom thereof.

[0028] Embodiment 2: On the basis of embodiment 1, in order to realize the card connection between the plug block 6 and the support seat 2 and improve the stability of the plug-in block 6, a slide groove 10 is provided on the separated side of the left and right plug blocks 6, and two push blocks 12 are installed on the inner wall of the slide groove 10. Elastic members 11 are installed between the front and rear push blocks 12, and a card plate 13 is installed on the separated side of the front and rear push blocks 12. Restriction grooves 14 are provided on the front and rear sides of the inner wall of the installation groove 7; the separated sides of the front and rear card plates 13 penetrate the plug block 6 and are plugged into the inner wall of the restriction groove 14, so that the card plate 13 is driven to move toward each other by pushing the two push blocks 12, so that one side of it is separated from the restriction groove 14, so that the user can remove the water tank connector 3, thereby improving the accuracy of the pressure sensor 4 monitoring, and the push block 12 is designed in an "I" shape to prevent it from being separated from the slide groove 10. At the same time, when the two push blocks 12 are pushed to move toward each other, the elastic member 11 is driven to be in an extruded state, thereby facilitating the subsequent reset of the card plate 13.

[0029] The two push blocks 12 are pushed to move toward each other along the inner wall of the slide groove 10, thereby driving the card plate 13 on one side thereof to disengage from the limiting groove 14, and driving the elastic member 11 to be in an extruded state on the inner wall of the slide groove 10, and then the push blocks 12 are pulled to both sides to drive the plug block 6 to gradually disengage from the card groove 9, and pull it out of the mounting groove 7, at this time, the water tank connector 3 can be disassembled to clean the scale on its inner wall, after completion, it is reset and inserted into the inner wall of the support seat 2 with the sealing ring 5, and the middle part of the through-through support seat 2 and the sealing ring 5 at the bottom of the water tank 1 is kept in a plug-in state, then the plug block 6 is reset, and one side of it penetrates the connecting groove 8 and is inserted into the inner wall of the card groove 9, and the two push blocks 12 are released at the same time, so that the elastic force of the elastic member 11 is used to drive the two push blocks 12 to move backwards, and then drive one side of the card plate 13 to be inserted into the inner wall of the limiting groove 14, so that the plug block 6 and the support seat 2 are clamped together, so that the support seat 2, the sealing ring 5 and the water tank connector 3 are installed more firmly.

[0030] Embodiment 3: On the basis of embodiment 2, in order to facilitate the separate replacement of the sealing ring 5 and improve the sealing between the support seat 2 and the water tank connector 3, positioning rods 15 are installed at the four corners of the inner top wall of the sealing ring 5, positioning grooves 16 are opened at the four corners of the top of the water tank connector 3, two mounting blocks 17 are installed on the left and right sides of the water tank connector 3, and rubber clamping columns 18 are installed at the four corners of the bottom of the sealing ring 5; the positioning rod 15 is inserted into the inner wall of the positioning groove 16, so that the sealing ring 5 can be installed conveniently by using the positioning rod 15; the rubber clamping column 18 is inserted into the inner wall of the mounting block 17, and the lower part of the rubber clamping column 18 is in an extruded deformation state, so that the setting of the rubber clamping column 18 can indirectly increase the friction between the sealing ring 5 and the water tank connector 3, thereby improving the firmness of its installation.

[0031] When the sealing ring 5 needs to be replaced, first pull out the plug blocks 6 on both sides, then remove the water tank connector 3, and then pull the sealing ring 5 upwards to drive the rubber clamping columns 18 at the four corners of its bottom to disengage from the mounting block 17, and at the same time drive the positioning rod 15 to disengage from the positioning groove 16.

At the same time, the sealing ring 5 is used to increase the sealing between the support seat 2 and the water tank connector 3 to prevent water leakage.

[0032] In actual use, first push the two push blocks 12 to move toward each other along the inner wall of the slide groove 10, thereby driving the card plate 13 on one side to disengage from the limiting groove 14, and driving the elastic member 11 to be squeezed on the inner wall of the slide groove 10, and then pull the push blocks 12 to both sides to drive the plug block 6 to gradually disengage from the card groove 9, and pull it out of the installation groove 7. At this time, the water tank connector 3 can be disassembled to clean the scale on its inner wall. After completion, reset it and use the sealing ring 5 to insert it into the inner wall of the support seat 2, and keep the middle part of the penetrating support seat 2 and the sealing ring 5 at the bottom of the water tank 1 plugged in, then reset the plug block 6, let one side of it penetrate the connecting groove 8, and insert it into the inner wall of the card groove 9, and release the two push blocks at the same time. The two push blocks 12 are driven by the elastic force of the elastic member 11 to move in reverse, thereby driving one side of the card plate 13 to be inserted into the inner wall of the limiting groove 14, so as to clamp the insert block 6 and the support seat 2 together, thereby making the support seat 2, the sealing ring 5 and the water tank connector 3 more firmly installed. When in use, water is poured into the water tank 1 and injected into the inner wall of the water tank connector 3 through the pipe at the bottom thereof. At this time, the pressure sensor 4 is used to monitor the pressure of the water inside the water tank 1 in real time, and then the pressure of the water level change is converted into a voltage signal, which is processed by the single chip microcomputer and then the water volume information displayed on the machine user operation interface is given or the machine recognition data is supported, so that the user can check the water volume at any time.

[0033] When the sealing ring 5 needs to be replaced, first pull out the plug blocks 6 on both sides, then remove the water tank connector 3, and then pull the sealing ring 5 upwards to drive the rubber clamping columns 18 at the four corners of its bottom to disengage from the mounting block 17, and at the same time drive the positioning rod 15 to disengage from the positioning groove 16. At this time, the sealing ring 5 can be replaced. After completion, the replaced sealing ring 5 is installed on the top of the water tank connector 3, and the positioning rod 15 is inserted into the inner wall of the positioning groove 16 to facilitate the user to install it. At the same time, the rubber clamping column 18 is inserted into the inner wall of the mounting block 17 and allowed to be deformed, thereby indirectly increasing the installation firmness between the sealing ring 5 and the water tank connector 3, thereby facilitating the subsequent user to disassemble and replace it. At the same time, the sealing ring 5 is used to increase the sealing between the support seat 2 and the water tank connector 3 to prevent water leakage.
