Description

Technical Field

[0002] At present, some tea bar machines are equipped with a capacitive sensor for detecting whether the water flow in the water pipe is in a water vapor mixed state. The capacitive sensor usually uses a soft water pipe to pass through a hard shell, and then uses the detection component in the shell to detect whether the water flow in the water pipe is in a water vapor mixed state. However, the sealing performance of the existing capacitive sensor is poor. Under the influence of humid weather and water vapor, water vapor or water mist will enter the shell through the gap of the shell connection and the gap between the shell and the water pipe, thereby causing the detection board of the capacitive sensor to be damp or damaged by water and unable to work, which affects the service life of the capacitive sensor.

[0034] The utility model provides an embodiment of a capacitive sensor, which is mainly used in drinking water equipment to detect whether there is gas in the liquid in the water pipe of the drinking water equipment. The drinking water equipment is a tea bar machine, a water purifier or a water dispenser.

[0035] See also Figure 1 and Figure 2 In one embodiment of the utility model, the capacitive sensor 300 includes a shell 310, a detection component 320 and a sealing member 330; an installation port 312a is provided on one opposite side of the shell 310, and a first water pipe hole 311a is provided on the other side for the water supply pipe 700 to pass through; the detection component 320 is arranged in the shell 310, and the detection component 320 includes a detection board 321 and a detection coil 322, the detection coil 322 is connected to the detection board 321, and the detection coil 322 is formed with a through hole 322a for the water supply pipe 700 to pass through; the sealing member 330 is sealed in the installation port 312a, and the sealing member 330 is provided with a second water pipe hole 331 for the water supply pipe 700 to pass through.

[0036] Specifically, the housing 310 of the capacitive sensor 300 is roughly rectangular, the water pipe 700 can pass through the housing 310 from opposite sides in the length direction, and the detection component 320 is arranged in the housing 310 to detect the state of the water flowing through the water pipe 700. The detection component 320 includes a detection plate 321 and a detection coil 322, the detection coil 322 is connected to the detection plate 321, and the detection coil 322 is formed with a through hole 322a through which the water supply pipe 700 passes. The shape of the detection coil 322 is roughly spring-shaped, and two pins are led out from both ends of the length direction of the detection coil 322 and connected to the detection plate 321. The detection coil 322 is formed with a through hole 322a through which the water supply pipe 700 passes, which can be understood as the detection coil 322 is sleeved on the outer wall of the water pipe 700 to more efficiently and comprehensively detect the state of the water flowing through the water pipe 700. The material of the detection coil 322 is preferably 304 stainless steel.

[0037] See also Figures 1 to 4 Specifically, since the water pipe 700 needs to pass through the opposite sides of the housing 310 to be detected by the detection assembly 320 located in the housing 310, the opposite sides of the housing 310 are respectively provided with an installation port 312a and a first water pipe hole 311a. The first water pipe hole 311a is used for the water pipe 700 to pass through. In order to ensure the sealing between the first water pipe hole 311a and the water pipe 700 after installation, the first water pipe hole 311a and the water pipe 700 are configured as an interference fit. Similarly, since the detection board 321 is installed in the housing 310, and the detection board 321 is electrically connected to the control module of the tea bar machine 10, in order to prevent the detection board 321 from being damaged by water or water vapor entering the housing 310, a sealing member 330 is also provided at the installation port 312a to seal the installation port 312a. The sealing member 330 and the installation port 312a can be configured as an interference fit to further improve the sealing of the housing 310. The sealing member 330 is made of silicone or rubber. A second water pipe hole 331 for the water pipe 700 to pass through is provided on the sealing member 330 to facilitate the water pipe 700 to pass through from opposite sides of the housing 310 .

[0038] See also Figure 2 Furthermore, in order to ensure the detection accuracy and rapid response of the detection component 320, the number of the detection coils 322 is set to at least two, at least two detection coils 322 are arranged on the detection board 321 at intervals, and the through holes 322a of at least two detection coils 322 are coaxial. The number of the detection coils 322 can be 2, 3, or 4, for example. Considering the overall volume of the capacitive sensor 300, as well as the detection performance, response time, etc., the number of the detection coils 322 is preferably set to two, and the two detection coils 322 are arranged side by side on the detection board 321 and connected to the detection board 321.

[0039] The technical solution of the utility model is to provide a sealing member 330 at the installation opening 312a of the shell 310 of the capacitive sensor 300, and seal the installation opening 312a by the sealing member 330, so as to prevent the influence of humid weather and water vapor, and prevent water vapor or water mist from entering the shell 310, thereby causing the detection board 321 to be damaged by moisture or water ingress and unable to work, thereby further improving the service life of the capacitive sensor 300.

[0040] See also Figure 3 and Figure 4 In one embodiment, a card slot 332 is formed on the peripheral side of the seal 330, and the seal 330 is carded in the installation opening 312a. Specifically, the seal 330 is carded and installed in the installation opening 312a, and the installation method is simple and convenient. Furthermore, the seal 330 and the installation opening 312a are interference-fitted, which can further prevent water mist and the like from entering the housing 310 and causing damage to the detection plate 321. Among them, the interference amount of the interference fit between the seal 330 and the installation opening 312a can be set to approximately 20%.

[0041] It is worth mentioning that the width of the slot 332 is less than or equal to the wall thickness at the installation port 312a. Specifically, since the seal 330 has a certain thickness and the slot 332 is formed on the peripheral side of the seal 330, the slot 332 is a sink 312b formed on the peripheral side of the seal 330. The width of the slot 332 refers to the width between the two side walls of the sink 312b; the wall thickness at the installation port 312a refers to the thickness of the housing 310 at the installation port 312a where the installation port 312a is opened. The slot width of the slot 332 can be less than the wall thickness at the installation port 312a, or it can be equal to the wall thickness at the installation port 312a. It only needs to ensure that the slot width of the slot 332 is not greater than the wall thickness at the installation port 312a. Preferably, the slot width of the slot 332 is slightly smaller than the wall thickness at the installation port 312a to ensure the stability of the clamping at the slot 332 and the installation port 312a and the sealing between the two.

[0042] See also Figure 3 and Figure 4In one embodiment, the sealing member 330 is provided with a wire-passing opening 333, and the capacitive sensor 300 further includes a data line 340, one end of the data line 340 is electrically connected to the detection board 321, and the other end extends out of the wire-passing opening 333, and the data line 340 and the wire-passing opening 333 are sealed and matched. Specifically, since the two ends of the data line 340 are respectively used to electrically connect the detection board 321 and other circuits in the tea bar machine 10, in order to facilitate the routing of the data line 340, the wire-passing opening 333 is configured as a notch provided on the sealing member 330, and the data line 340 and the wire-passing opening 333 are sealed and matched to prevent water mist from entering the housing 310 from the wire-passing opening 333 and damaging the detection board 321.

[0043] See also Figure 3 and Figure 4 In one embodiment, a limiting slot 313 is provided in the housing 310, and the detection plate 321 is provided in the limiting slot 313. The setting of the limiting slot 313 facilitates the installation of the detection plate 321 on the one hand, and also facilitates the position of the limiting plate installed in the housing 310 for limiting and fixing, so as to prevent the position from being shifted when subjected to external force, thereby affecting the detection effect.

[0044] Furthermore, the limiting slide groove 313 includes a first slide groove (not marked in the figure) arranged in the bottom shell 311 and a second slide groove (not marked in the figure) arranged in the end cover 312. When the detection plate 321 is installed in the shell 310, the position of the detection plate 321 is limited by the first slide groove and the second slide groove to avoid the position of the limiting plate from being offset.

[0045] In one embodiment, the first water pipe hole 311a, the second water pipe hole 331 and the through hole 322a are coaxially arranged to facilitate the assembly between the water pipe 700 and the capacitive sensor 300.

[0046] As for the installation method of the detection component 320, in one embodiment, the detection component 320 can be directly installed in the housing 310 through the installation port 312a, and then the housing 310 is sealed by the sealing member 330 disposed in the installation port 312a. In another embodiment, the housing 310 includes a bottom shell 311 and an end cover 312, and the bottom shell 311 and the end cover 312 are connected together by snapping, and the detection component 320 can be first installed in the bottom shell 311, and then the end cover 312 is sleeved on one end of the bottom shell 311 and the two are snapped together to achieve the installation of the detection component 320.

[0047] See also Figure 4On the basis of the previous embodiment, the end cover 312 is provided with a sink groove 312b corresponding to the bottom shell 311. When the bottom shell 311 and the end cover 312 are engaged, the end of the bottom shell 311 extends into the sink groove 312b, or the end surface of the bottom shell 311 abuts against the bottom of the sink groove 312b. Specifically, a sink groove 312b is provided on the edge of the end cover 312 corresponding to the bottom shell 311. When the bottom shell 311 and the end cover 312 are engaged, the end of the bottom shell 311 can extend into the sink groove 312b at least partially, or can extend into the sink groove 312b completely and abut against the bottom of the sink groove 312b. Through the design of the groove 312b, the edge of the end cover 312 can cover the edge of the bottom shell 311, avoiding an obvious gap between the bottom shell 311 and the end cover 312 after the two are snapped together, and preventing water vapor or water mist from entering the shell 310 through the fitting between the bottom shell 311 and the end cover 312, further improving the waterproof performance of the capacitive sensor 300, and avoiding the situation where the detection board 321 is damaged by moisture or water and cannot work.

[0048] See also Figures 5 to 8 The utility model also proposes a tea bar machine 10, which includes a body 100, an instant heating component 200 and the aforementioned capacitive sensor 300; the body 100 has a water storage chamber 111 for placing a water storage component 20, and a first water outlet 131 is arranged on the body 100; the instant heating component 200 is arranged in the body 100, and the instant heating component 200 has an instant heating water inlet 210 and an instant heating water outlet 220, the instant heating water inlet 210 is connected with the water storage component 20 through a water pipe 700, and the instant heating water outlet 220 is connected with the first water outlet 131 through the water pipe 700; the capacitive sensor 300 is arranged in the body 100, and is located upstream of the instant heating component 200, and the capacitive sensor 300 is used to detect whether there is gas in the liquid in the water pipe 700 passing through it. The specific structure of the capacitive sensor 300 refers to the above embodiment. Since the tea bar machine 10 adopts all the technical solutions of all the above embodiments, it at least has all the beneficial effects brought by the technical solutions of the above embodiments, which will not be described one by one here.

[0049] The body 100 of the utility model extends in the vertical direction as a whole, and a water storage chamber 111 is formed in the body 100 for placing a water storage member 20, and the water storage member 20 is used to store drinking water for users. The water storage member 20 can be a replaceable bottled water, or a pure water tank set in the body 100, or a pure water tank that can be replaced by the user, and there is no specific limitation on this. The material of the body 100 is a hard material, and as for the type of the hard material, it can be a hard material such as ABS, HIPS, PP, PC, or a metal or alloy material, etc., and there is no specific limitation on this.

[0050] The instant heating component 200 is arranged in the body 100. The instant heating technology applied to the tea bar machine 10 has the following advantages: 1. Energy saving. Heat as needed, and there is no need for long-term heating and heat preservation and other hot water storage work inside the machine, which reduces energy loss. 2. The product volume is reduced and the spatial adaptability is high. Because there is no need for hot water storage inside the machine, the structural design can reduce the product volume. 3. Low cost. Because there is no need for water storage hot filling and related heating detection components inside the machine, the product cost can be reduced. 4. Improved user experience. Users can set the water outlet temperature and water output as needed. The temperature control module and volume calculation module inside the machine quickly and accurately reach the target temperature by heating and adjusting the water flow rate to meet the user's water output needs. The instant hot water inlet 210 of the instant hot water component 200 of this embodiment is connected to the water storage component 20 through the water pipe 700, and the instant hot water outlet 220 is connected to the first water outlet 131 through the water pipe 700. The instant hot water component 200 can heat the water flowing through it. When the instant hot water component 200 is working, the water flowing through the instant hot water component 200 will be heated and flow out from the first water outlet 131 for user use.

[0051] The tea bar machine 10 of the utility model can have a variety of water outlet temperatures when hot water is discharged, and the water outlet temperature range of the hot water can be between 45°C and 95°C, and can be 45°C, 50°C, 55°C, 60°C, 65°C, 70°C, 75°C, 80°C, 85°C, 90°C, and 95°C for example. The water outlet temperature can be preset when the tea bar machine 10 leaves the factory, or can be configured with corresponding water outlet temperatures corresponding to a variety of hot water outlet states, and can also be set by the user as required, and there is no specific limitation on this.

[0052] See also Figure 5 and Figure 8In actual use, the tea bar machine 10 is a water pipe 700 inserted into the water storage part 20. The water in the water storage part 20 is pumped into the water pipe 700 through the pumping assembly and finally flows out from the water outlet for the user to use. It is considered that when the water in the water storage part 20 reaches the bottom, the water inlet 700 of the water pipe 700 may be partially covered by water and partially exposed to the air. In this case, the water pumped up by the water pump will be a discontinuous state of one section of water and one section of gas. At different water levels, the ratio of water to gas can be various values. Since the outlet water temperature required for tea making is generally high, for example, above 95°C, that is, in normal use, the water is heated to 95°C after passing through the heating tube and falls into the user's cup. However, when the water bucket reaches the bottom, the water volume entering the heating tube is sharply reduced in the state of water vapor mixing, while the heating power of the heating tube remains the original value, which will cause the outlet water temperature to increase instantly. The outlet water temperature is already around 95°C. Once the temperature is raised, it will enter a boiling state. The water delivered to the user will vaporize and expand, and the outlet water will be in a jet-like state. On the one hand, this state may splash onto the user and cause burns. On the other hand, due to the sudden decrease in the water in the instant heating pipe, local dry burning will occur, which is not good for user safety and the reliability of the whole machine. In view of this, a capacitive sensor 300 is also provided in the body 100. The capacitive sensor 300 is located upstream of the instant heating component 200. The capacitive sensor 300 can be clamped on the outer wall of the water pipe 700. The capacitive sensor 300 detects whether there is gas in the liquid flowing in the water pipe 700, thereby judging whether the water in the water pipe 700 is in a state of water vapor mixing, and then judging whether there is a lack of water in the water storage part 20, so as to avoid the water vapor mixing liquid splashing onto the user when the water is discharged, causing burns. At the same time, it also prevents the water in the instant heating component 200 from suddenly decreasing, thereby causing dry burning, affecting the service life of the instant heating component 200.

[0053] See also Figure 8 The capacitance sensor 300 is located upstream of the instant heating component 200, which means that the instant heating water inlet 210 of the instant heating component 200 is connected to the water storage component 20 through a pipeline. When the water flows in the pipeline, the capacitance sensor 300 is located upstream of the flow path, that is, the water drawn from the water storage component 20 will first flow through the capacitance sensor 300, and then flow into the instant heating component 200 for heating. The state of the water flow in the water pipe 700 is judged in advance by the capacitance sensor 300 in front to avoid water in a water vapor mixed state from flowing into the instant heating component 200 for heating.

[0054] Furthermore, a first water pump 610 is also provided upstream of the instant heating component 200, so as to pump water into the instant heating component 200 through the first water pump 610. In particular, since the capacitive sensor 300 needs a certain amount of water to pass through when judging the state of the water flow, and needs time to respond, in order to prevent the water flow in the state of water vapor mixed with the water flowing quickly from flowing into the instant heating component 200, the position of the capacitive sensor 300 can be set at a place far away from the instant heating component 200, preferably upstream of the first water pump 610.

[0055] The working principle of the capacitive sensor 300 of the present invention when applied to the tea bar machine 10 is as follows:

[0056] When the capacitance sensor 300 is applied to the tea bar machine 10, the water pipe 700 is installed by putting the two detection coils 322 of the capacitance sensor 300 on the water pipe 700 to be tested, and then pushing it into the housing 310. The capacitance sensor 300 detects the change of the object to be tested (i.e., water flow) in the pipe and outputs the corresponding state; when water flow is detected, a low level is output, and when bubbles (i.e., no water or water vapor mixture) are detected, a high level is output; by outputting different level states, it is judged whether there is gas in the liquid flowing in the water pipe 700. More specifically, the capacitance sensor 300 uses these two detection coils 322 as detection electrodes. When water flows through the detection coils 322, the change in the dielectric constant of water causes the capacitance to increase. The built-in microprocessor chip of the sensor collects the capacitance change law to judge the water / no water state, and outputs a low level / high level signal to represent the water / no water state in real time.

[0057] If the capacitive sensor 300 detects that the liquid flowing in the water pipe 700 contains gas, the tea bar machine 10 has multiple corresponding response states, among which the first state corresponding to the tea bar machine 10 is that the instant heating component 200 stops working, that is, the instant heating component 200 does not perform heating work, and the water flowing through the instant heating component 200 and out of the first water outlet 131 is water that has not been heated by the instant heating component 200; the second state corresponding to the tea bar machine 10 is that the first water outlet 131 stops discharging instant hot water, that is, at this time, the first water pump 610 located on the instant heating water outlet path does not work, and does not perform water pumping work, and the water flow cannot be pumped out and flows out from the first water outlet 131; the third state corresponding to the tea bar machine 10 is that the tea bar machine 10 directly stops working, that is, at this time, the entire tea bar machine 10 stops working.

[0058] See also Figure 5 and Figure 8It should be noted here that the number of water outlets of the tea bar machine 10 of the present application can be multiple, and the water outlet modes of the tea bar machine 10 can be multiple (for example, instant hot water outlet, normal temperature water outlet or refrigerated water outlet). The difference between the second and third states corresponding to the aforementioned tea bar machine 10 is that when the corresponding state of the tea bar machine 10 is in the second state, that is, the first water outlet 131 stops discharging instant hot water, this state only refers to the first water outlet 131 stopping discharging hot water heated by the instant heating component 200, but can still discharge cooling water or normal temperature water, and other water outlets can continue to discharge water without being affected; when the corresponding state of the tea bar machine 10 is in the third state, that is, the tea bar machine 10 stops working, at this time, the water pumps in the tea bar machine 10 stop working, and all the water outlets of the whole machine do not discharge water, and water needs to be replenished or a new water storage component 20 is replaced before water can be supplied again.

[0059] Please continue reading Figure 5 and Figure 8 In one embodiment, a second water outlet 132 is further provided on the body 100, and a reversing valve 500 is also provided in the body 100. The reversing valve 500 has a reversing water inlet 510, a first reversing water outlet 520 and a second reversing water outlet 530. The reversing water inlet 510 is connected to the instant hot water outlet 220, the first reversing water outlet 520 is connected to the first water outlet 131, and the second reversing water outlet 530 is connected to the second water outlet 132.

[0060] Specifically, in order to avoid hot water splashing and scalding the user when hot water is discharged, it is necessary to control the flow rate when hot water is discharged. Therefore, the first water outlet 131 used for discharging hot water has a smaller diameter. However, when discharging warm water normally, the first water outlet 131 with a smaller diameter is difficult to meet the water discharge demand. Therefore, a second water outlet 132 is also provided on the body 100, and a reversing valve 500 is provided in the body 100. The reversing valve 500 is used to switch the water path, so that when the tea bar machine 10 discharges hot water, the hot water flows out from the first water outlet 131 through the switching of the reversing valve 500, and when the tea bar machine 10 discharges normal temperature water, the normal temperature water flows out from the second water outlet 132 through the switching of the reversing valve 500.

[0061] See also Figure 5 and Figure 6 In one embodiment, the body 100 includes a main body 110, a bar support portion 120 and a bar portion 130. The main body 110 has a water receiving table 112 for placing a kettle. One side of the bar support portion 120 is connected to the water receiving table 112, and the other side of the bar support portion 120 is connected to the bar portion 130. The capacitive sensor 300 is arranged on the main body 110, the thermal component 200 is arranged on the bar support portion 120, and the first water outlet 131 is arranged on the bar portion 130.

[0062] Specifically, the main body 110 is roughly rectangular in design, and a water storage chamber 111 for placing the water storage member 20 is formed in the main body 110. When in use, a water receiving platform 112 for placing a kettle is formed on the upper surface of the main body 110. The bar support 120 is erected on the water receiving platform 112, and the instant heating component 200 is arranged in the bar support 120, so as to avoid more space in the main body 110 to install other structures, and the bar 130 provided with a first water outlet 131 is connected to the bar support 120, and the instant heating component 200 is closer to the first water outlet 131, and the water outlet path of the hot water heated by the instant heating component 200 is shorter, which can reduce heat loss.

[0063] See also Figure 6 and Figure 7 In one embodiment, the tea bar machine 10 further includes a refrigeration component 400, which is disposed in the body 100. One end of the refrigeration component 400 is connected to the water storage part 20, and the other end is connected to the first water outlet 131. Specifically, the refrigeration component 400 is disposed in the main body 110, and the refrigeration component 400 includes an electronic ice tank, a heat sink, a heat dissipation fan, etc. The water in the water storage part 20 can be cooled by the refrigeration component 400 for drinking by the user. One end of the refrigeration component 400 is connected to the water storage part 20, and the other end is connected to the first water outlet 131. A second water pump 620 can be separately provided on the water path of the refrigeration component 400 to provide power for the water outlet path of the refrigeration component 400.
