DETAILED DESCRIPTION

[0030] Exemplary embodiments of the present application will be described more fully hereinafter with reference to the accompanying drawings. While exemplary embodiments of the present application are shown in the drawings, it is to be understood that the present application can be embodied in various forms without being limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the present application to those skilled in the art.

[0031] With reference to Figures 1-4 , an embodiment of the present application provides a liquid storage device, which can include a box body 1, a box cover 2, a liquid inlet pipe 3, a liquid outlet pipe 4, an air permeable member 5, a first liquid level switch 6, and a first actuator 7, wherein:

[0032] The box cover 2 is located on the box body 1 and seals the box body 1, and the liquid inlet pipe 3 and the liquid outlet pipe 4 are respectively arranged through the box cover 2.

[0033] In the embodiment of the present application, the material of the box body 1 can be made of metal material. In the case that the liquid storage device is applied to a water dispenser or a pipeline machine and other liquid processing equipment related to food, the corresponding box body 1 can be made of food-grade stainless steel, such as 304 stainless steel and 316 stainless steel. The opening of the box body 1 is vertically upward, and the box cover 2 is fixed on the box body 1 to form a seal inside the box body 1, so as to avoid external impurities from entering the inside of the box body 1 and causing pollution to the liquid inside the box body 1. Penetrating can be understood as the liquid inlet pipe 3 and the liquid outlet pipe 4 extending to the inside of the box body 1 through the box cover 2 away from the end of the box body 1.

[0034] In one example, in order to improve the connection sealing between the box cover 2 and the liquid inlet pipe 3, the box cover 2 and the liquid inlet pipe 3 can be an integral structure; in another example, in order to improve the connection sealing between the box cover 2 and the liquid outlet pipe 4, the box cover 2 and the liquid outlet pipe 4 can be an integral structure; in another example, in order to improve the connection sealing between the box cover 2 and the liquid inlet pipe 3, and the connection sealing between the box cover 2 and the liquid outlet pipe 4, the box cover 2, the liquid inlet pipe 3 and the liquid outlet pipe 4 can be an integral structure. The box cover 2 can be made of the same metal material as the box body 1. For example, the box cover 2 can also be made of food-grade stainless steel, such as 304 stainless steel and 316 stainless steel. The person skilled in the art can determine the material of the box cover 2 and the box body 1 according to the actual design requirements, which is not limited here.

[0035] The air permeable member 5 is located on the box cover 2 to balance the air pressure inside and outside the box body 1. The first liquid level switch 6 is located in the box body 1, and the first liquid level switch 6 is closed when the liquid level drops to the lower limit liquid level. The bottom height of the liquid inlet pipe 3 and the bottom height of the liquid outlet pipe 4 are respectively lower than the lower limit liquid level.

[0036] In this embodiment of the invention, the cover 2 may have a vent hole for the installation of the vent 5. The vent 5 is installed in the vent hole to form an air passage connection between the inside and outside of the housing 1. Thus, the vent 5 can balance the air pressure inside the housing 1 and outside the device, while also preventing external impurities from entering the housing 1 through the vent 5 and contaminating the liquid inside the housing 1, thereby ensuring smooth liquid discharge from the outlet pipe 4 and the inlet pipe 3. Compared to the fine holes opened on the side of the housing 1 in the prior art, the vent 5 can completely eliminate the air pressure difference between the inside and outside of the housing 1, thereby reducing the pressure required for liquid extraction without contaminating the liquid inside the housing 1. This reduces the flow rate of the liquid inside the housing 1, maintains stable air pressure in the inlet pipe 3, outlet pipe 4, and inside the housing, and thus ensures smooth liquid discharge from the outlet pipe 4 and the inlet pipe 3.

[0037] The lower limit liquid level can be understood as the lowest liquid level height inside the tank 1 when the first liquid level switch 6 changes from the open state to the closed state. Those skilled in the art can determine the specific lower limit liquid level based on the installation position of the first liquid level switch 6 on the device. For example, the lower limit liquid level can be 3mm, 4mm, or 5mm, etc., without further limitation here. The bottom height of the inlet pipe 3 and the bottom height of the outlet pipe 4 are both lower than the lower limit liquid level. That is, when the liquid storage device performs inlet and outlet operations, the outlet of the inlet pipe 3 and the inlet of the outlet pipe 4 are always kept below the liquid height (liquid level). This reduces the noise generated by the inlet and outlet flow through the liquid.

[0038] The liquid height is the depth of the liquid inside the tank 1; the bottom height of the inlet pipe 3 is the vertical distance between the inner bottom of the tank 1 and the bottom end of the inlet pipe 3, such as... Figure 2 The bottom height of the inlet pipe 3 shown is h1; the bottom height of the outlet pipe 4 is the vertical distance between the inner bottom of the box 1 and the bottom end of the outlet pipe 4, as shown. Figure 2 The bottom height of the outlet pipe 4 shown is h2. For example, when the lower limit liquid level is 3mm, the bottom height h1 of the inlet pipe 3 can be 2mm, and the bottom height h2 of the outlet pipe 4 can be 2.5mm. As another example, the bottom height h1 of the inlet pipe 3 can be 2mm, and the bottom height h2 of the outlet pipe 4 can be 2mm. Those skilled in the art can determine the bottom heights of the inlet pipe 3 and the outlet pipe 4 according to actual design requirements; no further limitations are imposed here.

[0039] The first actuator 7 is installed on the liquid inlet pipe 3, and the power supply circuit of the first actuator 7 is coupled with the first liquid level switch 6, so that the first actuator 7 is powered when the first liquid level switch 6 is closed to deliver liquid into the box 1.

[0040] In the embodiment of the present application, the first actuator 7 is used to control the opening and closing of the liquid path in the liquid inlet pipe 3. For example, the first actuator 7 can be an electromagnetic valve, so that the opening and closing of the valve of the electromagnetic valve can control the opening and closing of the liquid path in the liquid inlet pipe 3. When the electromagnetic valve is powered, the valve of the corresponding electromagnetic valve is in an open state, so that the liquid in the liquid inlet pipe 3 flows smoothly, and the liquid flows into the box 1. When the electromagnetic valve is powered off, the valve of the corresponding electromagnetic valve is in a closed state, so that the liquid flow in the liquid inlet pipe 3 is cut off, and the liquid level in the box 1 no longer rises.

[0041] The first liquid level switch 6 can include an adjusting switch and a sensing module. When the sensing module detects that the liquid level reaches the lower limit, the adjusting switch will automatically change the switch state (i.e., the adjusting switch is switched from the off state to the closed state). Thus, the control switch of the first liquid level switch 6 can be coupled in the power supply circuit of the first actuator 7, so that the opening and closing state of the electromagnetic valve can be automatically adjusted by the first liquid level switch 6 based on the detected liquid level. When the liquid level in the box 1 is too low, the electromagnetic valve is powered on, and the valve is opened, so that the liquid can enter the box 1, thereby ensuring the minimum storage amount of liquid in the box 1.

[0042] On the one hand, the air permeable member 5 balances the air pressure inside and outside the box 1, so that the liquid can be transported in a smaller pressure environment. On the other hand, the first actuator 7 located on the box cover 2 can enter the liquid inlet pipe 3 after the external liquid enters the first actuator 7, which can reduce the kinetic energy (also known as flow rate) of the liquid, thereby further reducing the noise generated by the liquid inlet, and keeping the liquid extraction in the box 1 smooth, thereby optimizing the product performance of the liquid storage device.

[0043] In an alternative embodiment of the present application, a part of the bottom of the box 1 is protruding downward, and the liquid inlet pipe 3 and the liquid outlet pipe 4 extend to the inner bottom of the protruding box 1.

[0044] In the embodiment of the present application, with reference to Figure 1 and Figure 2As shown, the bottom of the box 1 is concave, which can increase the liquid storage space in the box 1, and increase the liquid storage capacity. In addition, the height of the liquid storage space can be increased, so that the depth of the liquid inlet pipe 3 and the liquid outlet pipe 4 in the box 1 can be extended, i.e. extending above the inner bottom of the concave part of the box 1. In this way, the length of the corresponding liquid flow channel in the liquid inlet pipe 3 and the liquid outlet pipe 4 can be extended, so as to reduce the noise of the liquid flow. For example, the cross-sectional shape of the box 1 is T-shaped.

[0045] In an optional embodiment of the application, the bottom of the liquid inlet pipe 3 and the bottom of the liquid outlet pipe 4 are flush.

[0046] As a preferred embodiment of the application, flush can be understood as the bottom height of the liquid inlet pipe 3 and the bottom height of the liquid outlet pipe 4 are consistent. Referring to Figure 2 As shown, the bottom height h1 of the liquid inlet pipe 3 and the bottom height h2 of the liquid outlet pipe 4 are the same. In this way, the control of the box cover 2 can be more convenient, and in the case of determining the bottom height of the liquid inlet pipe 3 or determining that the bottom height of the liquid outlet pipe 4 is lower than the lower limit liquid level. It can be determined that the liquid inlet port of the liquid inlet pipe 3 and the liquid outlet port of the liquid outlet pipe 4 are always below the liquid level during the liquid storage device performs liquid inlet operation and liquid outlet operation.

[0047] In an example, the bottom height of the liquid inlet pipe 3 and the bottom height of the liquid outlet pipe 4 can be as small as possible, for example, the bottom height h1 and the bottom height h2 can be 2mm. In this way, the greater the height difference between the bottom height of the liquid inlet pipe 3 and the bottom height of the liquid outlet pipe 4 and the lower limit liquid level, the greater the buoyancy when the corresponding liquid is discharged or inlet, so as to further reduce the noise generated when the liquid flows. In addition, when the bottom height of the liquid inlet pipe 3 and the bottom height of the liquid outlet pipe 4 are small, they are closer to the inner bottom of the box 1, so that the liquid at the bottom of the box 1 can be circulated when the liquid flows, and the liquid at the bottom of the box 1 can be avoided. The liquid at the bottom of the box 1 is stored for too long.

[0048] In an optional embodiment of the application, the air permeable member 5 is a filter screen.

[0049] In the embodiment of the application, referring to Figure 1 , Figure 2 and Figure 4As shown in the drawings, when the air permeable member 5 is a filter screen, the air pressure inside and outside the box body 1 can be kept consistent, and small impurities outside the device can be prevented from entering the box body 1 to pollute the liquid in the box body 1. The air permeable member 5 can be an air permeable film, which is a filter screen with a small pore size and can allow air to pass through but not liquid, thereby protecting the liquid in the box body 1 on the basis of balancing the air pressure.

[0050] In an optional embodiment of the application, a clamping groove 201 is formed in the edge of the box cover 2 close to the box body 1, and the clamping groove 201 is in clearance fit with the edge of the box body 1, wherein the box cover 2 and the box body 1 are fixed by welding.

[0051] In the embodiment of the application, as shown in Figure 3 The clearance fit of the clamping groove 201 and the edge of the box body 1 can increase the contact area of the box body 1 and the box cover 2, thereby improving the connection sealing performance of the liquid storage device. When the box cover 2 and the box body 1 are fixed by welding, the connection sealing performance of the liquid storage device can be further improved. Therefore, no sealing member is needed at the connection between the box cover 2 and the box body 1, and the aging of the sealing member does not need to be considered in the later use process, thereby improving the overall service life of the liquid storage device.

[0052] In an optional embodiment of the application, as shown in Figure 2 and Figure 3 The thickness of the box cover 2 is relatively small, and displacement or deformation may occur during the welding of the box cover 2 and the box body 1. A plurality of reinforcing ribs 11 are arranged on the end surface of the box cover 2 close to the box body 1, wherein the plurality of reinforcing ribs 11 are arranged at intervals on the box cover 2, and the plurality of reinforcing ribs 11 can be an integral structure with the box cover 2. In this way, the plurality of reinforcing ribs 11 can improve the structural strength of the box cover 2 on the one hand, and can act as counterweights on the other hand, so that the overall center of gravity of the box cover 2 is close to the box body 1 when the box cover 2 is placed on the box body 1. Therefore, the connection stability during the welding of the box body 1 and the box cover 2 can be improved, and displacement or deformation of the box cover 2 can be avoided.

[0053] In an optional embodiment of the application, as shown in Figure 1 and Figure 2 The first actuator 7 can include a first liquid inlet and a first liquid outlet, and the first liquid outlet of the first actuator 7 is in liquid communication with the liquid inlet pipe 3. The device further includes a liquid guide pipe 8, which penetrates the box body 1 and the box cover 2 and is in liquid communication with the first liquid inlet of the first actuator 7.

[0054] In the embodiment of the present application, in order to save the assembly space of the liquid storage device, the liquid guide pipe 8 penetrates through the box body 1 and the box cover 2, that is, the external liquid flows from the bottom of the liquid storage device to the top of the box cover 2 through the liquid guide pipe 8, and the liquid in the liquid guide pipe 8 is introduced into the first actuator 7 through the first liquid inlet in communication with the liquid inlet flow path, so that the liquid flow path from the liquid guide pipe 8 to the first actuator 7 and the liquid flow path from the first actuator 7 to the liquid inlet pipe 3 are bent together, which reduces the flow rate of the liquid and reduces the noise generated by the liquid flow.

[0055] In an optional embodiment of the present application, the inner bottom of the box body 1 is upwardly protruded to form a limiting portion 9 for the liquid guide pipe 8 to penetrate through, wherein the device further comprises a first sealing ring, which is sleeved on the liquid guide pipe 8 and is in pressure contact with the limiting portion 9.

[0056] In the embodiment of the present application, considering that the liquid guide pipe 8 penetrates through the box cover 2 and the box body 1 at the same time, and the liquid guide pipe 8 is in an integrated structure with the box cover 2 or the box body 1, the processing difficulty of the liquid storage device is greatly improved. Figure 1 and Figure 2 As shown in FIGS. 1 and 2, the liquid guide pipe 8 can be in clearance fit with the box cover 2, and the liquid guide pipe 8 can be in clearance fit with the box body 1. The inner bottom of the box body 1 can be upwardly protruded to form a limiting portion 9, and the limiting portion 9 is provided with a fixing hole, and the liquid guide pipe 8 penetrates through the fixing hole and is in clearance fit with the limiting portion 9. The limiting portion 9 can be in an integrated structure with the box body 1, and the integrated design can ensure the connection sealing between the box body 1 and the limiting portion 9. In addition, the limiting portion 9 can increase the contact area between the liquid guide pipe 8 and the box body 1, so as to avoid the shaking of the liquid guide pipe 8 and the generation of noise.

[0057] In an example, the liquid guide pipe 8 can be made of PVC (Polyvinyl chloride), PP (Polypropylene), silica gel and the like, which can be a hose or a hard pipe, and the first sealing ring can be sleeved on the liquid guide pipe 8 and in pressure contact with the limiting portion 9. In this way, the connection sealing between the liquid guide pipe 8 and the limiting portion 9 can be improved, and the liquid in the box body 1 can be prevented from leaking through the connecting portion of the limiting portion 9 and the liquid guide pipe 8. Correspondingly, the connecting portion of the liquid guide pipe 8 and the box cover 2 can also be provided with a second sealing ring for improving the connection sealing between the liquid guide pipe 8 and the box cover 2.

[0058] Further, in order to avoid the liquid in the tank 1 from leaking, the top end of the limiting part 9 can be higher than the upper limit liquid level in the tank 1.

[0059] In an alternative embodiment, the first liquid level switch 6 is a float type liquid level switch or a float ball type liquid level switch.

[0060] In the embodiment, referring to Figure 1 In the case that the first liquid level switch 6 is a float type liquid level switch, the first liquid level switch 6 is installed on the tank cover 2, and the float of the float type liquid level switch can be regarded as a sensing module of the float type liquid level switch. The float is located in the tank 1 and detects the liquid level and changes by the relative position between the float and the liquid surface by using the principle of buoyancy. When the liquid level in the tank 1 reaches the lower limit liquid level, the float is in a static state, and the adjusting switch of the float type liquid level switch is switched from the open state to the closed state. Thus, the first actuator 7 is connected to the power supply, and the valve of the corresponding first actuator 7 is switched from the closed state to the open state, so that the liquid in the liquid inlet pipe 3 flows smoothly, and the liquid flows into the tank 1.

[0061] When the liquid in the tank 1 reaches the upper limit liquid level, the float is affected by the buoyancy of the liquid in the tank 1 and rises to the set position, and the adjusting switch of the float type liquid level switch is switched from the closed state to the open state. Thus, the first actuator 7 is disconnected from the power supply, and the valve of the corresponding first actuator 7 is switched from the open state to the closed state. At this time, the liquid flow in the liquid inlet pipe 3 is cut off, and the liquid level in the tank 1 no longer rises. Thus, the lower limit liquid level and the upper limit liquid level of the liquid in the tank 1 can be automatically controlled by one float type liquid level switch. Thus, the control circuit of the liquid storage device can be simplified, and the assembly space of the device can be reduced.

[0062] In another example, in the case that the first liquid level switch 6 is a float ball type liquid level switch, the working principle is similar to that of the float type liquid level switch. The float ball of the float ball type liquid level switch is located in the tank 1 and can float up and down with the change of the liquid in the tank 1. When the liquid level in the tank 1 reaches the lower limit liquid level, the float ball sinks, and thus the magnetic material inside the float ball is attracted to the magnetic material in the adjusting switch of the float ball type liquid level switch, so that the adjusting switch is switched from the open state to the closed state. Thus, the first actuator 7 is connected to the power supply, and the valve of the corresponding first actuator 7 is switched from the closed state to the open state, so that the liquid in the liquid inlet pipe 3 flows smoothly, and the liquid flows into the tank 1.

[0063] When the liquid level in the box 1 reaches the upper limit, the float ball rises, the magnetic material inside the float ball and the magnetic material inside the regulating switch are separated due to buoyancy, and the regulating switch is switched from the closed state to the open state. Thus, the first actuator 7 is disconnected from the power supply, and the valve corresponding to the first actuator 7 is switched from the open state to the closed state. At this time, the liquid flow in the liquid inlet pipe 3 is cut off, and the liquid level in the box 1 stops rising. Thus, the lower limit and the upper limit of the liquid in the box 1 can be automatically controlled by using a float ball type liquid level switch.

[0064] In an alternative embodiment of the application, as shown in Figs. Figure 1 and Figure 2 The device further comprises a sterilization assembly 10 arranged inside the box 1 to sterilize the liquid in the box 1.

[0065] In the embodiment of the application, the sterilization assembly 10 can be a sterilization structure comprising an ultraviolet lamp. Thus, the sterilization assembly 10 can be arranged inside the box 1 to irradiate the inside of the box 1 with ultraviolet light when the sterilization assembly 10 is powered on, thereby sterilizing the liquid in the box 1 and the inner wall of the box 1.

[0066] The embodiment of the application further provides a liquid processing device, which comprises the liquid storage device according to any one of the above-mentioned embodiments of the application.

[0067] In the embodiment of the application, the liquid processing device can be a pipeline machine, a water dispenser, a beverage machine, a coffee machine, or other related devices involving liquid processing.

[0068] In an alternative embodiment of the application, the outer bottom of the liquid storage device is provided with a connecting rod, wherein the connecting rod can be provided with threads, so that the liquid storage device can be screwed onto the liquid processing device. In addition, corresponding connecting holes can be formed in the outer surface of the liquid storage device to facilitate the assembly of the liquid storage device.

[0069] In summary, the embodiment of the present application discloses a liquid storage device and a liquid processing device, which can include a box body 1, a box cover 2, a liquid inlet pipe 3, a liquid outlet pipe 4, a gas permeable member 5, a first liquid level switch 6 and a first actuator 7. The box cover 2 is located on the box body 1 and seals the box body 1, and the liquid inlet pipe 3 and the liquid outlet pipe 4 are respectively arranged through the box cover 2. The gas permeable member 5 is located on the box cover 2 to balance the air pressure inside and outside the box body 1. The first liquid level switch 6 is located in the box body 1, and the first liquid level switch 6 is closed when the liquid level drops to the lower limit liquid level, and the bottom height of the liquid inlet pipe 3 and the bottom height of the liquid outlet pipe 4 are respectively lower than the lower limit liquid level. The first actuator 7 is installed on the liquid inlet pipe 3, and the power supply circuit of the first actuator 7 is coupled with the first liquid level switch 6, so that the first actuator 7 is powered to deliver liquid into the box body 1 when the first liquid level switch 6 is closed. The gas permeable member 5 balances the air pressure inside and outside the box body 1, so that the liquid can be transported in a smaller pressure environment, and the bottom of the liquid inlet pipe 3 and the bottom of the liquid outlet pipe 4 are always below the liquid level in the box body 1, so that the liquid can be transported in a smaller pressure environment, thereby reducing the noise generated by the liquid inlet and outlet flow, and keeping the liquid extraction in the box body 1 smooth.
