Description

Technical Field

[0001] This utility model relates to the field of liquid level detection technology, specifically to a liquid level detection component and a drinking water purification device. Background Technology

[0002] Currently, most water purification devices, such as water purifiers and combined hot and cold water dispensers, have automatic water filling functions and usually include a liquid level detection device. This device uses the principle of communicating vessels to detect the water level in the tank and controls water filling and stopping through relevant programs. It can also automatically issue an alert when the water level is too low to remind users to add water. However, commonly used liquid level detection devices are susceptible to damage when the water in the tank is subjected to impacts, such as when the device is moved or struck. This can cause violent fluctuations in the water level within the detection device, leading to rapid changes in the liquid level and potentially causing the water filling or water shortage program to be incorrectly activated, thus affecting the user experience. Utility Model Content

[0003] In view of this, the present invention provides a liquid level detection component to solve the problem that when water in a water tank is subjected to impact, the violent oscillation of the liquid surface inside the tank causes rapid changes in the liquid level within the liquid level detection device, leading to the erroneous activation of the water addition or water shortage program. Simultaneously, the present invention provides a drinking water purification device.

[0004] In a first aspect, this utility model provides a liquid level detection component, which is connected to a water tank via a liquid guiding pipe, comprising: The main body of the communicating vessel is equipped with a liquid-containing cavity; A flow passage is connected to the liquid-containing cavity and can connect to the liquid guiding pipeline. The flow passage is provided with a first flow port and a second flow port. The first flow port is located at the end of the flow passage close to the liquid-containing cavity, and the second flow port is located at the end of the flow passage away from the liquid-containing cavity. The flow area of ​​the first flow port is smaller than the flow area of ​​the second flow port. Beneficial effects: This utility model provides a liquid level detection component. When the water in the water tank is impacted, because the flow area of ​​the first flow port of the flow channel is smaller than that of the second flow port, the water flow velocity at the first flow port of the flow channel will be slower than that at the second flow port. This slows down the flow velocity of the water flowing from the liquid guide pipe connected to the water tank into the liquid chamber of the communicating vessel body, as well as the flow velocity of the water flowing out of the liquid chamber into the liquid guide pipe. As a result, the change in the amount of water in the liquid chamber of the communicating vessel body is very small. Therefore, even if the liquid level in the water tank is violently shaken, the liquid level in the liquid level detection component can still increase or decrease steadily without rapid changes. This avoids the water filling or water shortage program of the water tank of the water purifier being erroneously activated when the water in the water tank is impacted.

[0005] In one alternative implementation, the inner diameter of the flow channel gradually decreases from the side furthest from the liquid cavity to the side closest to the liquid cavity.

[0014] Beneficial effects: The connecting rod connected to the flow channel facilitates the connection between the liquid guiding pipeline and the main body of the communicating vessel, resulting in a simple structure and stable connection.

[0015] In one optional embodiment, the liquid level detection assembly further includes a baffle disposed circumferentially along the connecting rod, the baffle being fixedly disposed on the communicating vessel body.

[0016] Beneficial effect: The baffles installed around the circumference of the connecting rod protect the connecting rod inside, preventing it from breaking due to impact during the handling of the entire water purifier or when it is subjected to a collision.

[0017] In one optional embodiment, the liquid level detection component further includes: A limiting structure is provided on the outer wall of the main body of the communicating vessel; The detection switch is snapped into the limiting structure and can form a position sensing with the float located in the liquid cavity.

[0018] Beneficial effects: The limiting structure provides a stable installation position for the detection switch, preventing the detection switch from shifting after being subjected to vibration and impact, and ensuring the detection accuracy of the liquid level detection component.

[0019] In one optional embodiment, the detection switch is provided with a mounting hole; The limiting structure includes a positioning post, a limiting rib, and a spring clip. The positioning post is inserted into the assembly hole, the limiting rib is used to limit the side of the detection switch, and the spring clip is used to engage the side of the detection switch.

[0020] Beneficial effects: The positioning posts, limiting ribs and spring clips on the outer wall of the communicating vessel body ensure that the position of the detection switch is limited and the installation is stable.

[0021] In one alternative embodiment, the top of the communicating vessel body is provided with an opening communicating with the liquid-containing cavity; The liquid level detection component also includes a dustproof structure disposed at the opening, the dustproof structure having a pore connecting the liquid chamber to the outside.

[0022] Beneficial effects: A porous dustproof structure is installed at the opening at the top of the communicating vessel body to ensure air pressure balance while preventing foreign objects from entering the communicating vessel body.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components.

[0033] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0034] The following is combined Figures 1-11 The following describes embodiments of the present invention.

[0035] According to an embodiment of the present invention, in one aspect, a liquid level detection component is provided, which is connected to a water tank 200 via a liquid guiding pipe 300, such as... Figure 1 , Figure 2 , Figure 3 As shown, it includes: a communicating vessel body 110 and a flow channel 120.

[0036] The main body 110 of the communicating vessel is provided with a liquid-containing cavity 111; the flow passage 120 is connected to the liquid-containing cavity 111 and can be connected to the liquid guiding pipe 300. The flow passage 120 is provided with a first flow port 121 and a second flow port 122. The first flow port 121 is located at the end of the flow passage 120 close to the liquid-containing cavity 111, and the second flow port 122 is located at the end of the flow passage 120 away from the liquid-containing cavity 111. The flow area of ​​the first flow port 121 is smaller than the flow area of ​​the second flow port 122. In the above embodiment, when the water in the water tank 200 is impacted, since the flow area of ​​the first flow port 121 of the flow channel 120 is smaller than that of the second flow port 122, the water flow velocity at the first flow port 121 of the flow channel 120 will be slower than that at the second flow port 122. This slows down the flow velocity of the water in the liquid guiding pipe 300 connected to the water tank 200 flowing into the liquid-containing cavity 111 of the communicating vessel body 110, as well as the flow velocity of the water flowing out of the liquid-containing cavity 111 into the liquid guiding pipe 300. As a result, the change in the amount of water in the liquid-containing cavity 111 of the communicating vessel body 110 is very small. Therefore, even if the liquid surface in the water tank 200 is violently shaken, the liquid level in the liquid level detection component can still increase or decrease steadily without rapid change, thus preventing the water filling or water shortage program from being erroneously activated when the water in the water tank of the water purification device is impacted.

[0037] Specifically, such as Figure 2 , Figure 3As shown, the main body 110 of the liquid level detection component is connected to the water tank 200 through the liquid guiding pipe 300 to form a communicating vessel. Utilizing the principle of communicating vessels, the liquid level in the water storage chamber of the water tank 200 can be reflected by the liquid level in the liquid-containing chamber 111 of the main body 110. The flow area of ​​the first flow port 121 is smaller than that of the second flow port 122. Since the flow channel 120 is connected to the liquid chamber 111, the flow area of ​​the first flow port 121 is naturally smaller than the cross-sectional area of ​​the liquid chamber 111. As a result, the outlet of the water in the liquid guide pipe 300 into the liquid chamber 111 will be smaller, and the water flow velocity will be slowed down. The outlet of the water in the liquid chamber 111 into the liquid guide pipe 300 will also be smaller, and the water flow velocity will also be slowed down. This makes the change in the amount of water in the liquid chamber 111 very small, and thus makes the liquid level in the liquid level detection component increase or decrease steadily. This avoids the frequent signaling of the liquid level sensing device, which causes the water tank 200 to be replenished and stopped intermittently.

[0038] Furthermore, such as Figure 2 , Figure 3 As shown, the flow area of ​​the first overflow port 121 is the range through which water is allowed to flow in the flow channel 120. For example, when the first overflow port 121 is constructed as a circle, the flow area of ​​the first overflow port 121 is the area of ​​the circle. The flow area of ​​the second overflow port 122 is similar.

[0039] Furthermore, this embodiment does not limit the specific configuration of the flow channel 120. In one implementation, the flow channel 120 is a pipe section, with the inner diameter of the end of the pipe near the liquid-containing cavity 111 being smaller than the inner diameter of the end away from the liquid-containing cavity 111. In another implementation, the flow channel 120 is a through-hole on a plate of a certain thickness, with the diameter of the through-hole on the side near the liquid-containing cavity 111 being smaller than the diameter on the side away from the liquid-containing cavity 111.

[0040] In some embodiments, such as Figure 2 , Figure 3 As shown, the inner diameter of the flow channel 120 gradually decreases from the side away from the liquid chamber 111 to the side closer to the liquid chamber 111.

[0041] In the above embodiment, the inner diameter of the flow channel 120 gradually decreases from the side away from the liquid chamber 111 to the side closer to the liquid chamber 111, thereby improving the flow stability of water flowing through the flow channel 120 and further improving the stability of liquid level changes in the liquid level detection component.

[0042] Specifically, such as Figure 2 , Figure 3As shown, by utilizing the linear and continuous change of the inner diameter of the flow channel 120, the flow area of ​​the first flow port 121 is made smaller than that of the second flow port 122. At the same time, since the inner diameter of the flow channel 120 changes linearly and continuously, the flow velocity of the water in the flow channel 120 also changes gradually, thereby improving the flow stability of the water flowing through the flow channel 120.

[0043] Furthermore, such as Figure 2 , Figure 3 As shown, in this embodiment, the flow channel 120 is arranged in the shape of a frustum, and the inner diameter of the flow channel 120 is the diameter of any cross-section of the frustum.

[0044] As an alternative implementation, the inner diameter of the flow channel 120 varies non-linearly, ensuring that the flow area of ​​the first flow port 121 is smaller than the flow area of ​​the second flow port 122.

[0045] In some embodiments, such as Figure 2 , Figure 3 As shown, the inner diameter of the first flow port 121 ranges from 0.7mm to 1.2mm, and the inner diameter of the second flow port 122 ranges from 3.5mm to 4.5mm.

[0046] In the above embodiments, the inner diameter range of the first overflow port 121 and the second overflow port 122 is limited to further ensure the flow stability of water flowing through the overflow channel 120.

[0047] Specifically, such as Figure 2 , Figure 3 As shown, in this embodiment, the flow channel 120 is arranged in the shape of a frustum. The inner diameter of the first flow port 121 is the diameter of the first flow port 121, and the inner diameter of the second flow port 122 is the diameter of the second flow port 122.

[0048] In some embodiments, such as Figure 2 , Figure 3 As shown, in a preferred embodiment, the inner diameter of the first flow port 121 is 1 mm, and the inner diameter of the second flow port 122 is 4 mm.

[0049] In the above embodiments, the optimal values ​​of the inner diameters of the first flow port 121 and the second flow port 122 are defined to further ensure the flow stability of water flowing through the flow channel 120.

[0050] In some embodiments, such as Figure 2 , Figure 3 As shown, the flow channel 120 is provided on the bottom wall 112 of the communicating vessel body 110, the first flow port 121 is located on the inner side of the bottom wall 112, and the second flow port 122 is located on the outer side of the bottom wall 112.

[0051] In the above embodiments, the flow channel 120 is directly constructed on the bottom wall 112 of the communicating vessel body 110, which simplifies the construction of the liquid level detection component.

[0052] Specifically, such as Figure 2 , Figure 3 The flow channel 120 is configured as a through hole in the bottom wall 112 of the main body 110 of the communicating vessel. The first flow port 121 of the flow channel 120 is located on the inner side of the bottom wall 112 and is flush with the inner side of the bottom wall 112; the second flow port 122 of the flow channel 120 is located on the outer side of the bottom wall 112 and is flush with the outer side of the bottom wall 112.

[0053] In some embodiments, such as Figure 2 , Figure 3 As shown, at least part of the bottom wall 112 of the communicating vessel body 110 extends away from the liquid chamber 111 to form a connecting rod 130. The connecting rod 130 is hollow and communicates with the flow channel 120. The liquid guiding pipe 300 is connected to the connecting rod 130 to communicate with the liquid chamber 111.

[0054] In the above embodiment, a connecting rod 130 is provided to communicate with the flow channel 120, which facilitates the connection between the liquid guiding pipeline 300 and the communicating vessel body 110. The structure is simple and the connection is stable.

[0055] Specifically, such as Figure 2 , Figure 3 As shown, in this embodiment, the connecting rod 130 is arranged along the periphery of the second flow port 122, so that the hollow inner cavity of the connecting rod 130 communicates with the flow channel 120. The connecting rod 130 is integrally formed into the communicating vessel body 110.

[0056] In some embodiments, such as Figure 1 , Figure 2 , Figure 3 As shown, the liquid level detection assembly also includes a baffle 140 arranged circumferentially along the connecting rod 130, and the baffle 140 is fixedly disposed on the communicating vessel body 110.

[0057] In the above embodiment, the baffle 140 arranged circumferentially along the connecting rod 130 provides protection for the connecting rod 130 inside it, preventing the connecting rod 130 from being broken by impact when the whole water purifier is transported or subjected to impact.

[0058] Specifically, such as Figure 1 , Figure 3 As shown, in this embodiment, there are two baffles 140, which are located on both sides of the connecting rod 130.

[0059] Furthermore, such as Figure 1 , Figure 3 As shown, the baffle 140 is integrally formed on the bottom wall 112 of the communicating vessel body 110.

[0060] In some embodiments, such as Figure 2 , Figure 4 , Figure 5 As shown, the liquid level detection assembly also includes a limiting structure 150 and a detection switch 160.

[0061] The limiting structure 150 is located on the outer wall of the main body 110 of the communicating vessel; the detection switch 160 is snapped into the limiting structure 150 and can form a position sensing with the float 170 located in the liquid cavity 111.

[0062] In the above embodiment, the limiting structure 150 provides a stable installation position for the detection switch 160, preventing the detection switch 160 from shifting after being subjected to vibration and impact, and ensuring the detection accuracy of the liquid level detection component.

[0063] Specifically, such as Figure 2 , Figure 4 , Figure 5 As shown, the detection switch 160 has two positions along the height of the communicating vessel body 110, corresponding to the high and low liquid levels of the liquid chamber 111 within the communicating vessel body 110. When the float 170 in the liquid chamber 111 rises and falls with the liquid level in the liquid chamber 111 to the high and low levels, the detection switch 160 and the float 170 form a position sensor, and send a signal to stop or begin water replenishment in the water tank 200. The limiting structure 150 limits the detection switch 160 to ensure that the float 170 forms a stable position sensor when rising and falling with the liquid level in the liquid chamber 111 to the high and low levels.

[0064] In some embodiments, such as Figure 4 , Figure 5 , Figure 6 , Figure 7 , Figure 8 As shown, the detection switch 160 is provided with an assembly hole 161; the limiting structure 150 includes a positioning post 151, a limiting rib 152 and a spring buckle 153. The positioning post 151 is inserted into the assembly hole 161, the limiting rib 152 is used to limit the side of the detection switch 160, and the spring buckle 153 is used to snap the side of the detection switch 160.

[0065] In the above embodiment, the positioning post 151, the limiting rib 152 and the spring buckle 153 provided on the outer wall of the communicating vessel body 110 are used to ensure that the position of the detection switch 160 is limited and the installation is stable.

[0066] Specifically, such as Figure 5 , Figure 6 , Figure 8As shown, during installation of the detection switch 160, the positioning pin 151 is inserted into the assembly hole 161 to form an insertion fit, the limiting rib 152 forms a limiting fit on the side of the detection switch 160, and the spring clip 153 forms a snap-fit ​​fit on the side of the detection switch 160. These three assembly points ensure the positional limitation and stable installation of the detection switch 160.

[0067] Furthermore, this embodiment does not limit the position and number of the positioning post 151, the limiting rib 152, and the spring clip 153. In this embodiment, as... Figure 5 , Figure 6 , Figure 8 As shown, the detection switch 160 has two mounting holes 161, two positioning posts 151 are provided corresponding to the two mounting holes 161, two limiting ribs 152 are provided on the left and right sides of the detection switch 160, and two spring clips 153 are provided on the top and bottom sides of the detection switch 160.

[0068] Furthermore, such as Figure 8 As shown, the two positioning posts 151 and the limiting rib 152 on at least one side are integrally formed, which facilitates demolding, reduces the thin steel structure, and improves the structural stability of the liquid level detection component.

[0069] In some embodiments, such as Figure 1 , Figure 2 , Figure 9 As shown, the top of the communicating vessel body 110 is provided with an opening 113 that communicates with the liquid chamber 111; the liquid level detection assembly also includes a dustproof structure 180 provided in the opening 113, and the dustproof structure 180 is provided with a hole 1831 that communicates with the liquid chamber 111 and the outside.

[0070] In the above embodiment, a dustproof structure 180 with pores 1831 is provided at the opening 113 at the top of the communicating vessel body 110 to ensure the air pressure balance of the communicating vessel while preventing foreign objects from entering the communicating vessel body 110.

[0071] Specifically, such as Figure 1 , Figure 2 , Figure 9 As shown, a conventional communicating vessel body 110 has an opening 113 at the top to ensure pressure balance, but it is also easy for dust and other foreign objects to fall in. In this embodiment, a dustproof structure 180 is provided at the opening 113 to prevent dust and other foreign objects from falling into the communicating vessel body 110; a pore 1831 is provided in the dustproof structure 180 to connect the liquid chamber 111 with the outside world to ensure pressure balance.

[0072] Furthermore, such as Figure 1 , Figure 2 , Figure 9As shown, the dustproof structure 180 includes a dust cover 181, a dustproof sponge 182, and a pressure cap 183. The dust cover 181 is made of food-grade silicone and forms an interference fit with the communicating vessel body 110; the pressure cap 183 forms an interference fit with the dust cover 181 and has a hole 1831 at the top. The dustproof sponge 182 is located between the pressure cap 183 and the dustproof sleeve 181 to prevent dust and other foreign objects from entering the liquid chamber 111 through the pores 1831, and to ensure that the liquid chamber 111 can be connected to the outside through the internal gaps of the dustproof sponge 182 and the pores 1831 of the pressure cap 183.

[0073] According to an embodiment of the present invention, another aspect also provides a water purification device, such as... Figure 10 As shown, it includes: a body 400, a water tank 200, a liquid level detection component 100 as described in the above embodiment, and a liquid guiding pipe 300.

[0074] The water tank 200 and the liquid level detection component 100 are respectively located on the body 400; the liquid guide pipe 300 is connected between the water outlet of the water tank 200 and the flow passage 120 of the liquid level detection component 100.

[0075] In the above embodiment, the communicating vessel body 110 of the liquid level detection component 100 is connected to the water tank 200 through the liquid guiding pipe 300 to form a communicating vessel. Utilizing the principle of communicating vessels, the liquid level in the water storage chamber of the water tank 200 can be reflected by the liquid level in the liquid-containing chamber 111 of the communicating vessel body 110. The optimized design of the liquid level detection component 100 avoids the incorrect activation of the water filling or water shortage program when the water in the water tank 200 of the drinking water equipment is impacted.

[0076] Specifically, such as Figure 10 As shown, the connecting rod 130 of the liquid level detection component 100 is connected to one end of the double-connector 310, and the other end of the double-connector 310 is connected to the liquid guide pipe 300. The liquid guide pipe 300 is connected to the water circuit board 500. After passing through the water circuit board 500 and subsequent components, it is led out through another section of the liquid guide pipe 300.
