Description

Technical Field

[0002] Purified drinking water equipment is a device that can filter raw water such as tap water, and then obtain pure water that is discharged from the water outlet for users to use. However, dripping or leakage is prone to occur at the water outlet, so a water tray is generally set below the water outlet to collect the dripping water. When the amount of water in the water tray reaches a certain level, it needs to be processed. Therefore, the water tray can be set to be detachable, so that when the water volume reaches a certain value, the user needs to remove the water tray and pour out the accumulated water in it; or the accumulated water in the water tray can be directed to other locations, which can prevent the water in the water tray from overflowing and eliminate the need for the user to remove and clean the water tray.

[0003] In actual applications, whether it is an automatic drain or a water tray that needs to be disassembled to drain the water, a liquid level detection device is usually installed in the water tray to detect the water level in the water tray, so that when the water level reaches a certain height, an early warning is issued to remind the user to disassemble the water tray to drain the water or start the automatic drain program to drain the water. The commonly used liquid level detection device is large in size and requires a large installation space. In addition, two liquid level detection devices need to be installed in the automatic drain water tray to detect low and high liquid levels. This will increase the cost of the water tray and occupy a relatively large space in the water purification equipment, which to a certain extent increases the size of the water purification equipment and increases the cost of the water purification equipment. In addition, it is also prone to detection errors.

[0051] Based on the existing water receiving tray pointed out in the background technology, to a certain extent, it increases the volume of the water purification equipment and increases the cost of the water purification equipment, and the problem of insufficient liquid level detection accuracy and errors. The water purification equipment of the present invention includes a shell, a water receiving assembly and a water level sensing capacitor. The water receiving assembly includes a water receiving tray with a water receiving cavity. The water receiving tray is detachably connected to the shell. The water level sensing capacitor is installed on the bottom wall of the shell. When the water receiving tray and the shell are installed, the bottom wall of the water receiving tray fits with the bottom wall of the shell, so that the water level sensing capacitor can detect the water level in the water receiving tray. In this setting, the water level sensing capacitor is used to detect the water level height in the water receiving tray.

It is preferred that the bottom wall of the water receiving tray 21 is in contact with the bottom wall of the shell 1, so that the water level sensing capacitor 3 can detect the capacitance value in the water receiving cavity 11 by separating the bottom wall of the water receiving tray 21, and then reflect the height of the water level in the water receiving cavity 11 by the change in the capacitance value.

[0054] The present invention adopts a water level sensing capacitor 3 to detect the water level height in the water receiving tray 21. It is small in size and low in cost, which can reduce the size of the water purification equipment and reduce the cost of the water purification equipment. In addition, the water level sensing capacitor 3 is installed on the outside of the water receiving tray 21, and sensing detection is performed through the plastic, which facilitates wiring arrangement and thus assembly and use, and facilitates the removal of the water receiving component 2 to pour out the water in the water receiving cavity 211.

[0055] It should be noted that the present invention does not impose any restrictions on the specific installation position of the water level sensing capacitor 3. In actual applications, as long as the water level sensing capacitor 3 can detect the water level change in the water receiving tray 21, those skilled in the art can set the installation position of the water level sensing capacitor 3 according to actual needs. For example, the water level sensing capacitor 3 can be set between the bottom wall of the water receiving tray 21 and the bottom wall of the housing 1, or the water level sensing capacitor 3 can be set on the side of the bottom wall of the housing 1 away from the water receiving tray 21, and so on. Any adjustment or change in the installation position of the water level sensing capacitor 3 does not deviate from the basic principles of the present invention and should be limited within the scope of protection of the present invention.

[0056] Preferably, please also refer to Figure 8 and Figure 9 The water level sensing capacitor 3 is installed on a side surface of the bottom wall of the housing 1 away from the water receiving tray 21.

[0057] The water level sensing capacitor 3 is installed on a side of the bottom wall of the shell 1 away from the water receiving tray 21, which is more convenient for assembly and disassembly and easy to use. In addition, the water level sensing capacitor 3 detects the water level through two layers of plastic, which can increase the distance between the water level sensing capacitor 3 and the metal parts in the water receiving assembly 2, thereby improving the detection accuracy.

[0058] In one embodiment, please also refer to Figures 6 to 9The bottom wall of the shell 1 protrudes upward to form a mounting groove 13, and the water level sensing capacitor 3 can be removably installed in the mounting groove 13. When the water level sensing capacitor 3 and the mounting groove 13 are installed, the water level sensing capacitor 3 is horizontally arranged, and its top surface is in contact with the bottom wall of the shell 1.

[0059] The bottom wall of the shell 1 protrudes upward to form a mounting groove 13, providing an installation space 11 for the water level sensing capacitor 3, which is convenient for installing the water level sensing capacitor 3. The water level sensing capacitor 3 is detachably installed in the mounting groove 13, which is convenient for assembly and disassembly, thereby facilitating maintenance; when the water level sensing capacitor 3 and the mounting groove 13 are installed, the water level sensing capacitor 3 is horizontally arranged, and its top surface is in contact with the bottom wall of the shell 1, which can effectively improve the detection accuracy of the water level sensing capacitor 3.

[0060] It should be noted that the present invention does not impose any restrictions on the specific connection method between the water level sensing capacitor 3 and the mounting slot 13. As long as the water level sensing capacitor 3 and the mounting slot 13 are detachably connected, in actual applications, those skilled in the art can set the specific connection method between the water level sensing capacitor 3 and the mounting slot 13 according to actual needs. For example, the water level sensing capacitor 3 can be installed in the mounting slot 13 via a locking member, or the water level sensing capacitor 3 can be clamped in the mounting slot 13 via a snap-fit ​​member, etc. Any adjustments and changes to the specific connection method between the water level sensing capacitor 3 and the mounting slot 13 do not deviate from the basic principles of the present invention and should be limited to the scope of protection of the present invention.

[0061] In one embodiment, please continue to refer to Figure 7 and Figure 9 The water purification device further includes a locking member (not labeled in the figure) disposed within the mounting groove 13. The locking member is configured to secure the water level sensing capacitor 3 within the mounting groove 13 and to restrict movement of the water level sensing capacitor 3 relative to the housing 1 along a first horizontal direction and a second horizontal direction, wherein the second horizontal direction is perpendicular to the first horizontal direction. Specifically, the first horizontal direction and the second horizontal direction are the width and length directions of the water level sensing capacitor 3, respectively.

[0062] By arranging a locking component in the installation groove 13, the locking component can fix the water level sensing capacitor 3 in the installation groove 13 and can limit the movement of the water level sensing capacitor 3 relative to the shell 1 along the first horizontal direction and the second horizontal direction. This setting method makes it easier to assemble and disassemble the water level sensing capacitor 3, reduces the difficulty of assembly, and is convenient to use.

[0063] In one embodiment, see Figure 9 and Figure 10A limiting member (not marked in the figure) is provided on the water level sensing capacitor 3. When the engaging member fixes the water level sensing capacitor 3 in the mounting groove 13, the limiting member cooperates with the engaging member to limit the movement of the water level sensing capacitor 3 relative to the housing 1 along the second horizontal direction and the vertical direction.

[0064] By setting a limiter and cooperating with the locking member, the water level sensing capacitor 3 can be restricted from moving relative to the shell 1 along the second horizontal direction and the vertical direction, thereby effectively improving the stability of the assembled water level sensing capacitor 3. At the same time, the water level sensing capacitor 3 can be tightly attached to the bottom wall of the shell 1, thereby ensuring the detection accuracy.

[0065] It should be noted that the present invention does not impose any restrictions on the specific structure of the locking component. In actual applications, those skilled in the art can set the specific structure of the locking component according to actual needs. Adjustments and changes to the specific structure of the locking component do not deviate from the basic principles of the present invention and should be limited within the scope of protection of the present invention.

[0066] In one embodiment, please also refer to Figures 6 to 9 The locking component includes two claws 41 arranged in the installation groove 13. The two claws 41 are arranged opposite to each other, and a locking cavity 6 for accommodating the water level sensing capacitor 3 is formed between the two claws 41. A locking end 42 is provided at one end of the claw 41. When the water level sensing capacitor 3 is located in the locking cavity 6, the two claws 41 can limit the water level sensing capacitor 3 to limit the movement of the water level sensing capacitor 3 relative to the housing 1 along the first horizontal direction; the locking end 42 cooperates with the groove wall of the installation groove 13 to limit the water level sensing capacitor 3 to limit the movement of the water level sensing capacitor 3 along the second horizontal direction.

A clamping end 42 is provided at one end of the clamping claw 41 for clamping the water level sensing capacitor 3. The structure is simple and the clamping and fixing effect of the water level sensing capacitor 3 is good.

[0068] In one embodiment, please also refer to Figure 9 and Figure 10 The limiting component includes two horizontal limiting plates 51 installed on the side walls of the water level sensing capacitor 3. The two horizontal limiting plates 51 are located on both sides of the water level sensing capacitor 3 along the first horizontal direction. A vertical limiting plate 43 is provided at the end of the claw 41 away from the engaging end 42. When the water level sensing capacitor 3 is located in the engaging cavity 6, the bottom wall of the horizontal limiting plate 51 abuts against the top wall of the adjacent claw 41, and the side surface of the horizontal limiting plate 51 away from the engaging end 42 abuts against the adjacent vertical limiting plate 43.

[0069] The limiting member includes two horizontal limiting plates 51, which abut against the top surface of the claw 41 to limit the movement of the water level sensing capacitor 3 in the vertical direction. The side of the horizontal limiting plate 51 away from the engaging end 42 abuts against the vertical limiting plate 43, thereby limiting the movement of the water level sensing capacitor 3 relative to the shell 1 along the second horizontal direction. This setting method has a simple structure, is easy to assemble and use, and effectively improves the limiting effect.

[0070] Preferably, see Figure 7 、 Figure 9 and Figure 10 The two engaging ends 42 are away from one end of the horizontal limiting plate 51 and have auxiliary inclined surfaces 421 on the opposite side surfaces, so that the water level sensing capacitor 3 can be smoothly inserted into the engaging cavity 6.

[0071] When installing the water level sensing capacitor 3, the auxiliary inclined surfaces 421 of the two engaging ends 42 contact the water level sensing capacitor 3, moving the water level sensing capacitor 3 toward the engaging cavity 6, thereby spreading the two claws 41. After the water level sensing capacitor 3 enters the engaging cavity 6, the two claws 41 return to their original positions, so that their engaging ends 42 abut against the side walls of the water level sensing capacitor 3, engaging the water level sensing capacitor 3 in the engaging cavity 6, and fixing the water level sensing capacitor 3.

[0073] This arrangement facilitates the assembly of the water receiving tray 21 and the housing 1 , while enabling the bottom wall of the water receiving tray 21 facing the water level sensing capacitor 3 to fit smoothly against the bottom wall of the housing 1 , thereby helping to improve the detection accuracy of the water level sensing capacitor 3 .

[0074] Preferably, the sum of the thicknesses of the bottom wall of the housing 1 directly above the water level sensing capacitor 3 and the bottom wall of the water receiving tray 21 is no greater than 1 cm.

[0075] The sum of the thicknesses of the bottom wall of the housing 1 directly above the water level sensing capacitor 3 and the bottom wall of the water receiving tray 21 is made no greater than 1 cm, thereby reducing the sensing thickness of the water level sensing capacitor 3, thereby effectively ensuring the detection accuracy of the water level sensing capacitor 3 and improving the accuracy of the detection results.

[0076] Preferably, the water purification device further includes a water pump, and a water pumping port is provided on the water receiving cavity 211 , and the water pump is connected to the water pumping port so as to be able to pump out the water in the water receiving cavity.

[0077] By setting a water suction port on the water receiving cavity 211 and setting a water pump connected to the water suction port, the water pump can pump out the water in the water receiving cavity 211 through the water suction port, thereby realizing automatic discharge of the water in the water receiving cavity 211. Automatic drainage can be realized by using the water level sensing capacitor 3 in conjunction with the water pump. When the capacitance value detected by the water level sensing capacitor 3 exceeds a certain value, the controller controls the water pump to work, pump out the water, and automatically drain the water, thereby effectively improving the convenience of use.

[0078] Preferably, the water receiving assembly 2 further includes a carrying plate 22, which is detachably mounted in the water receiving cavity 211 and is used to carry the water receiving container. The carrying plate 22 is provided with a plurality of water leakage holes 221. The carrying plate 22 facilitates the carrying of the water receiving container, thereby making it convenient for the user to place the water receiving container for water collection.

[0079] Preferably, a positioning step 14 is formed on the bottom wall of the shell 1, and a positioning plate 213 is provided on the side of the bottom wall of the water receiving tray 21 close to the bottom wall of the shell 1. When the water receiving tray 21 and the shell 1 are installed, the positioning plate 213 abuts against the positioning step 14.

[0080] By providing the positioning plate 213 and the positioning step 14, it is convenient to position the water receiving tray 21 and the shell 1 when they are installed. At the same time, when the installation is in place, the two can be judged to be in place by abutting against each other, and the positioning step 14 can share the impact force during installation, avoiding damage to the water level sensing capacitor 3 due to severe impact on the shell 1 to which the water level sensing capacitor 3 is attached due to excessive force.
