Description

Technical Field

[0001] The utility model relates to the technical field of drinking water equipment, in particular to a pipeline drinking water equipment. Background Art

[0002] A pipeline machine, also known as a pipeline drinking fountain, is generally used in families, offices, schools, etc., and is used in conjunction with a water purification device. The pipeline machine is provided with a water tank, and clean water is stored in the water tank in advance. After being heated or cooled by the pipeline machine, hot water or cold water can be supplied for users to drink.

[0003] The traditional pipeline drinking water equipment adopts an internal water tank, which makes it difficult to clean the water tank. A pipeline drinking water equipment in the related art adopts a water tank that can be disassembled from the host, making it easy to clean the water tank. However, the use of a detachable water tank also results in poor sealing performance at the interface between the water tank and the host, and leakage problems are likely to occur. Summary of the Utility Model

[0004] An embodiment of the utility model provides a pipeline drinking water equipment, in which the water tank and the host of the pipeline drinking water equipment can be disassembled from each other, and the interface position has good sealing performance.

[0005] An embodiment of the utility model provides a pipeline drinking water equipment, including a host, a water tank, an insertion pipe, a first sealing component, a sleeve and a second sealing component. The water tank is detachably arranged on the host; the insertion pipe is arranged on one of the host and the water tank; the first sealing component is connected to the insertion pipe, and the first sealing component has a first sealing state for blocking the insertion pipe and a first opening state for conducting the insertion pipe; the sleeve is arranged on the other of the host and the water tank, and the insertion pipe can be inserted into the sleeve; the second sealing component is connected to the sleeve, and the second sealing component has a second sealing state for blocking the sleeve and a second opening state for conducting the sleeve; wherein, when the water tank and the host are separated, the first sealing component is in the first sealing state, and the second sealing component is in the second sealing state; when the water tank is installed on the host, the first sealing component is in the first opening state, and the second sealing component is in the second opening state.

[0006] For the pipeline drinking water equipment according to the embodiments of the present utility model, when the water tank is connected to the main machine, at least part of the insertion pipe is located inside the sleeve, and the first sealing assembly is in the first open state, and the second sealing assembly is in the second open state. At this time, the water tank and the main machine are communicated via the insertion pipe and the sleeve; when the water tank and the main machine are separated, the first sealing assembly is in the first sealing state to block the insertion pipe to prevent the water in the water tank or the main machine from flowing out through the insertion pipe, and the second sealing assembly is in the second sealing state to block the sleeve to prevent the water in the water tank or the main machine from flowing out through the sleeve. In this way, it is realized that both the water tank and the main machine can be separately sealed after being disassembled from each other and can be communicated after being connected to each other. Thereby, the sealing performance at the interface between the water tank and the main machine can be improved, and the risk of water leakage can be reduced.

[0007] In some embodiments of the present utility model, the first sealing assembly includes a first seal, a first piston rod and a first elastic member. When the first sealing assembly is in the first sealing state, the first seal is in sealing contact with the insertion pipe to block the insertion pipe; the first piston rod is connected to the first seal; the first elastic member is connected to the first piston rod and is also connected to the insertion pipe; wherein, when at least part of the insertion pipe is inserted into the sleeve, the first piston rod and the second sealing assembly are mutually extruded, so that the first seal moves to release the block of the insertion pipe by the first seal.

[0008] Based on the above embodiments, the first piston rod can move relative to the insertion pipe along the axial direction of the insertion pipe when subjected to an external force. When the water tank and the main machine are connected to each other, at least part of the insertion pipe is located inside the sleeve, and the first piston rod and the second sealing assembly are mutually extruded to compress the first elastic member, so that the first piston rod drives the first seal to move to the first open state. At this time, the water tank and the main machine are conducted via the insertion pipe and the sleeve; when the water tank and the main machine are separated from each other, the first piston rod loses the external acting force, and the first piston rod drives the first seal to return to the first sealing state under the action of the first elastic member.

[0009] In some embodiments of the present utility model, the insertion pipe includes a first pipe body part and a first limiting part. The first pipe body part is connected to the main machine or the water tank. When the first sealing assembly is in the first sealing state, the first seal is in sealing contact with the first pipe body part; the first limiting part is located inside the first pipe body part and is connected to the first pipe body part. The inner diameter of the first limiting part is smaller than the inner diameter of the first pipe body part, and the first elastic member is clamped between the first limiting part and the end of the first piston rod away from the first seal.

[0010] Based on the above embodiments, after the first elastic member is clamped between the first limiting portion and the end of the first piston rod away from the first seal, the first elastic member causes the first piston rod to have a tendency to move towards the sleeve. However, the first limiting portion is clamped between the first elastic member and the first seal, and the first seal restricts the first piston rod from moving towards the sleeve. At this time, the force on the first piston rod reaches equilibrium, and it can only move away from the water tank when acted upon by an external force, thereby fixing the first seal assembly in the insertion pipe. Moreover, under the action of the first elastic member, the first seal is tightly connected to the first pipe body portion.

[0011] In some embodiments of the present utility model, the second seal assembly includes a second seal, a second piston rod, and a second elastic member. When the second seal assembly is in the second sealed state, the second seal is in sealing contact with the sleeve to block the sleeve; the second piston rod is connected to the second seal; the second elastic member is connected to the second piston rod and is also connected to the sleeve; when at least a part of the insertion pipe is inserted into the sleeve, the first piston rod and the second piston rod are mutually pressed, so that the second piston rod drives the second seal to move, thereby releasing the blockage of the sleeve by the second seal.

[0012] Based on the above embodiments, the second piston rod can move relative to the insertion pipe along the axial direction of the insertion pipe when acted upon by an external force. When the water tank and the main machine are connected to each other, at least a part of the insertion pipe is inside the sleeve, and the second piston rod and the first piston rod are mutually pressed to compress the second elastic member, so that the second piston rod drives the second seal to move to the second open state. At this time, the water tank and the main machine are conducted through the insertion pipe and the sleeve; when the water tank and the main machine are separated from each other, the second piston rod loses the external force, and the second piston rod drives the second seal to return to the second sealed state under the action of the second elastic member.

[0013] In some embodiments of the present utility model, the sleeve includes a second pipe body portion and a second limiting portion. The second pipe body portion is connected to the main machine or the water tank, and the second seal is in sealing contact with the second pipe body portion; the second limiting portion is inside the second pipe body portion and protrudes from the inner pipe wall of the second pipe body portion, and the first elastic member is clamped between the first limiting portion and the end of the first piston rod away from the first seal.

[0014] Based on the above embodiments, after the second elastic member is clamped between the second limiting portion and the end of the second piston rod away from the second seal, the second elastic member causes the second piston rod to have a tendency to move towards the insertion pipe. However, the second limiting portion is clamped between the second elastic member and the second seal, and the second seal restricts the second piston rod from moving towards the sleeve. At this time, the force on the second piston rod reaches equilibrium, and it can only move away from the water tank when acted upon by an external force, achieving the fixation of the second seal assembly within the sleeve. Moreover, under the action of the second elastic member, the second seal is tightly connected to the second pipe body portion.

[0015] In some embodiments of the present utility model, the pipeline drinking water device further includes a third seal, which is located within the second pipe body portion and is in sealed contact with the inner pipe wall of the second pipe body portion. When at least a part of the insertion pipe is inserted into the sleeve, the third seal is in sealed contact with the outer pipe wall of the first pipe body portion.

[0016] Based on the above embodiments, at least a part of the insertion pipe is within the sleeve, the third seal is in sealed connection with the outer pipe wall of the first pipe body portion and the inner pipe wall of the second pipe body portion, ensuring the sealed connection between the insertion pipe and the sleeve when the water tank and the main body are interconnected.

[0017] In some embodiments of the present utility model, the water tank includes a main body portion and a handle portion that are interconnected. A receiving cavity is recessed on the side of the main body portion away from the main body, and the handle portion is within the receiving cavity and only occupies a part of the space of the receiving cavity.

[0018] Based on the above embodiments, the handle facilitates the user to separate the water tank from the main body.

[0019] In some embodiments of the present utility model, the pipeline drinking water device further includes a detection circuit and a triggering member. The detection circuit includes a detecting member and an indicator light, and both the detecting member and the indicator light are fixed to the main body; the triggering member is fixed to the water tank, and when the triggering member touches the detecting member, the detection circuit is turned on.

[0020] Based on the above embodiments, when the triggering member triggers the detecting member, the detection circuit is turned on, and the indicator light emits light to indicate that the water tank and the main body are interconnected.

[0021] In some embodiments of the present utility model, the detecting member is configured as a reed switch, and the triggering member is configured as a magnetic member.

[0022] Based on the above embodiments, a reed switch is an electric switch operated by an applied magnetic field. When the reed switch is subjected to a magnetic force, two magnetic reed pieces within the reed switch come into contact with each other under the action of the magnetic force, turning on the detection circuit and causing the indicator light to emit light.

[0023] In some embodiments of the present utility model, the triggering member is located on the side of the water tank close to the main body, and the detecting member is located on the side of the main body close to the water tank, and the triggering member is arranged opposite to the detecting member.

[0024] Based on the above embodiments, the detecting member and the triggering member are arranged oppositely to ensure that the triggering member can definitely trigger the detecting member when the water tank and the main body are connected to each other. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0033] In order to make the objectives, technical solutions and advantages of the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0034] A pipeline machine, also known as a pipeline water dispenser, is generally used in families, offices, schools, etc., and is used in conjunction with a water purification device. The pipeline machine is provided with a water tank, and clean water is stored in the water tank in advance. After being heated or cooled by the pipeline machine, hot water or cold water can be supplied for users to drink.

[0035] Traditional pipeline drinking water equipment uses an internal water tank, which makes it difficult to clean the water tank. A pipeline drinking water equipment in related technologies uses a water tank that can be disassembled from the main unit, making it easy to clean the water tank. However, using a detachable water tank also results in poor sealing at the interface between the water tank and the main unit, and it is easy to have a leakage problem.

[0036] To solve the above technical problems, please refer to Figures 1 to 3 As shown in the figure, an embodiment of the present utility model provides a pipeline drinking water equipment, in which the main unit 10 and the water tank 20 of the pipeline drinking water equipment can be disassembled from each other, and the interface position has good sealing performance.

[0037] Please refer to Figures 1 to 3 As shown in the figure, the pipeline drinking water equipment includes a main unit 10, a water tank 20, an insertion pipe 30, a first sealing component 40, a sleeve 50, and a second sealing component 60. The water tank 20 is detachably arranged on the main unit 10; the insertion pipe 30 is arranged on one of the main unit 10 and the water tank 20; the first sealing component 40 is connected to the insertion pipe 30, and the first sealing component 40 has a first sealing state for blocking the insertion pipe 30 and a first opening state for conducting the insertion pipe 30; the sleeve 50 is arranged on the other of the main unit 10 and the water tank 20, and the insertion pipe 30 can be inserted into the sleeve 50; the second sealing component 60 is connected to the sleeve 50, and the second sealing component 60 has a second sealing state for blocking the sleeve 50 and a second opening state for conducting the sleeve 50; wherein, when the water tank 20 and the main unit 10 are separated, the first sealing component 40 is in the first sealing state, and the second sealing component 60 is in the second sealing state; when the water tank 20 is installed on the main unit 10, the first sealing component 40 is in the first opening state, and the second sealing component 60 is in the second opening state.

[0038] Based on the pipeline drinking water device of the embodiment of the present utility model, when the water tank 20 is connected to the main unit 10, at least a part of the insertion pipe 30 is located inside the sleeve 50, and the first sealing assembly 40 is in the first open state, and the second sealing assembly 60 is in the second open state. At this time, the water tank 20 and the main unit 10 are communicated via the insertion pipe 30 and the sleeve 50; when the water tank 20 and the main unit 10 are separated, the first sealing assembly 40 is in the first sealing state to block the insertion pipe 30 to prevent the water in the water tank 20 or the main unit 10 from flowing out through the insertion pipe 30, and the second sealing assembly 60 is in the second sealing state to block the sleeve 50 to prevent the water in the water tank 20 or the main unit 10 from flowing out through the sleeve 50. In this way, it is realized that both the water tank 20 and the main unit 10 can be separately sealed after being disassembled from each other, and can be communicated after being connected to each other. Thus, the sealing performance at the interface between the water tank 20 and the main unit 10 can be improved, and the risk of water leakage can be reduced.

[0039] It can be understood that the main unit 10 is fixed on the wall. After the main unit 10 and the water tank 20 are disassembled, the user must move the water tank 20 away from the main unit 10. In some embodiments of the present utility model, the insertion pipe 30 can be fixed on the main unit 10 and protrude from the surface of the main unit 10. The sleeve 50 can be fixed inside the water tank 20 and communicate the inner surface and the outer surface of the water tank 20. At this time, although the insertion pipe 30 protrudes from the surface of the main unit 10, the main unit 10 does not move, and the probability of damaging the insertion pipe 30 is small. Although the sleeve 50 is fixed on the water tank 20 moved by the user, the sleeve 50 is arranged inside the water tank 20, and the probability of noise damage to the sleeve 50 is small. In this way, the probability of damage to the pipeline drinking water device during disassembly and cleaning is reduced.

[0040] Furthermore, the insertion pipe 30 can be integrally formed with the housing of the main unit 10, and the sleeve 50 can be integrally formed with the water tank 20. In this way, the sealing performance between the insertion pipe 30 and the housing of the main unit 10, and the sealing performance between the sleeve 50 and the water tank 20 are ensured through the manufacturing process.

[0041] Please refer to Figure 3 As shown, in some embodiments of the present utility model, the first sealing assembly 40 includes a first seal 41, a first piston rod 42, and a first elastic member 43. When the first sealing assembly 40 is in the first sealing state, the first seal 41 is in sealing contact with the insertion pipe 30 to block the insertion pipe 30; the first piston rod 42 is connected to the first seal 41; the first elastic member 43 is connected to the first piston rod 42, and the first elastic member 43 is connected to the insertion pipe 30; wherein, when at least a part of the insertion pipe 30 is inserted into the sleeve 50, the first piston rod 42 and the second sealing assembly 60 are mutually pressed, so that the first seal 41 moves to release the block of the first seal 41 on the insertion pipe 30.

[0042] The first piston rod 42 can move relative to the insertion pipe 30 along the axial direction of the insertion pipe 30 when subjected to an external force. When the water tank 20 is interconnected with the main unit 10, at least a part of the insertion pipe 30 is located within the sleeve 50. The first piston rod 42 and the second sealing assembly 60 are pressed against each other to compress the first elastic member 43, causing the first piston rod 42 to drive the first seal 41 to move to the first open state. At this time, the water tank 20 and the main unit 10 are communicated via the insertion pipe 30 and the sleeve 50. When the water tank 20 is separated from the main unit 10, the first piston rod 42 loses the external force, and the first piston rod 42 drives the first seal 41 to return to the first sealed state under the action of the first elastic member 43.

[0043] The first seal 41 is used to block the insertion pipe 30. In some embodiments of the present invention, the first seal 41 is sealingly connected to the end face of the insertion pipe 30 connected to the main unit 10. In some other embodiments of the present invention, the insertion pipe 30 includes an insertion section and a connection section connected to each other. The connection section is connected to the main unit 10, and at least a part of the insertion section is inserted into the sleeve 50. The inner diameter of the connection section is larger than the inner diameter of the insertion section to form a shoulder between the connection section and the insertion section. When the first sealing assembly 40 is in the first sealed state, the first seal 41 is in sealing contact with the shoulder to block the insertion pipe 30. At this time, the first seal 41 is located within the connection section.

[0044] The first piston rod 42 is used to mount the first seal 41 and drive the first seal 41 to move along the axial direction of the insertion pipe 30. In some embodiments of the present invention, the first piston rod 42 includes a main body section, a connection section, and a limiting section. The connection section is connected to one end of the main body section and is connected to the first seal 41. The limiting section is connected to the other end of the main body section, and the first elastic member 43 is clamped between the limiting section and the first limiting portion 32.

[0045] Combined with the above-mentioned sealing connection between the first seal 41 and the end face of the insertion pipe 30 connected to the main unit 10, when the first sealing assembly 40 is in the sealed state, the connection section is outside the insertion pipe 30, and the limiting section and the main body section are inside the insertion pipe 30. When the first sealing assembly 40 is in the open state, a part of the main body section is outside the insertion pipe 30.

[0046] Combined with the above-mentioned insertion pipe 30 including an insertion section and a connection section connected to each other, the connection section is connected to the main unit 10, and at least a part of the insertion section is inserted into the sleeve 50. The inner diameter of the connection section is larger than the inner diameter of the insertion section to form a shoulder between the connection section and the insertion section. When the first sealing assembly 40 is in the first sealed state, the first seal 41 is in sealing contact with the shoulder to block the insertion pipe 30. When the first sealing assembly 40 is in the sealed state, the connection section is inside the connection section, and the limiting section and the main body section are inside the insertion section. When the first sealing assembly 40 is in the open state, the connection section and a part of the main body section are inside the insertion section.

[0047] The first elastic member 43 is used to provide the power for the first piston rod 42 and the first seal 41 to return to the initial position. In some embodiments of the present invention, the first elastic member 43 can be configured as a spring, and when the first sealing assembly 40 is in the first sealing state, the first elastic member 43 has elastic potential energy. Thus, when the first sealing assembly 40 is in the first sealing state, the elastic potential energy of the first elastic member 43 causes the first seal 41 to be in close contact with the insertion pipe 30. It can be understood that the greater the elastic potential energy of the first elastic member 43 when the first sealing assembly 40 is in the first sealing state, the closer the contact between the first seal 41 and the insertion pipe 30, and the better the sealing performance between the two.

[0048] Please refer to Figure 3 and Figure 4 As shown, in some embodiments of the present invention, the insertion pipe 30 includes a first pipe body portion 31 and a first limiting portion 32. The first pipe body portion 31 is connected to the main body 10 or the water tank 20. When the first sealing assembly 40 is in the first sealing state, the first seal 41 is in sealing contact with the first pipe body portion 31; the first limiting portion 32 is located inside the first pipe body portion 31 and is connected to the first pipe body portion 31. The inner diameter of the first limiting portion 32 is smaller than the inner diameter of the first pipe body portion 31. The first elastic member 43 is clamped between the first limiting portion 32 and the end of the first piston rod 42 away from the first seal 41. The first limiting portion 32 is located between the first elastic member 43 and the first seal 41.

[0049] After the first elastic member 43 is clamped between the first limiting portion 32 and the end of the first piston rod 42 away from the first seal 41, the first elastic member 43 makes the first piston rod 42 tend to move towards the sleeve 50. However, the first limiting portion 32 is clamped between the first elastic member 43 and the first seal 41, and the first seal 41 restricts the first piston rod 42 from moving towards the sleeve 50. At this time, the force on the first piston rod 42 reaches equilibrium, and it can only move away from the water tank 20 when acted upon by an external force, realizing the fixation of the first sealing assembly 40 in the insertion pipe 30, and the first seal 41 is tightly connected to the first pipe body portion 31 under the action of the first elastic member 43.

[0050] In the embodiments of the present invention, the first limiting portion 32 can protrude from the inner pipe wall of the first pipe body portion 31, so that a shoulder is formed between the first pipe body portion 31 and the first limiting portion 32. And in order to better fix the first elastic member 43, in some embodiments of the present invention, the first limiting portion 32 is configured as an annular limiting portion.

[0051] Among them, the first open state means that the first seal 41 is completely separated from the first pipe body portion 31.

[0052] Please refer to Figure 5 and Figure 6As shown, in some embodiments of the present utility model, the second sealing assembly 60 includes a second seal 61, a second piston rod 62, and a second elastic member 63. When the second sealing assembly 60 is in the second sealing state, the second seal 61 is in sealing contact with the sleeve 50 to block the sleeve 50; the second piston rod 62 is connected to the second seal 61; the second elastic member 63 is connected to the second piston rod 62 and is also connected to the sleeve 50. When at least a part of the insertion pipe 30 is inserted into the sleeve 50, the first piston rod 42 and the second piston rod 62 are mutually pressed, so that the second piston rod 62 drives the second seal 61 to move, thereby releasing the blockage of the sleeve 50 by the second seal 61.

[0053] The second piston rod 62 can move relative to the insertion pipe 30 along the axial direction of the insertion pipe 30 when subjected to an external force. When the water tank 20 and the main unit 10 are connected to each other, at least a part of the insertion pipe 30 is inside the sleeve 50, and the second piston rod 62 and the first piston rod 42 are mutually pressed to compress the second elastic member 63, so that the second piston rod 62 drives the second seal 61 to move to the second open state. At this time, the water tank 20 and the main unit 10 are communicated via the insertion pipe 30 and the sleeve 50; when the water tank 20 and the main unit 10 are separated from each other, the second piston rod 62 loses the external acting force, and the second piston rod 62 drives the second seal 61 to return to the second sealing state under the action of the second elastic member 63.

[0054] In the embodiments of the present utility model, the structures of the second piston rod 62, the second seal 61, and the second elastic member 63 are the same as those of the second piston rod 62, the second seal 61, and the first elastic member 43 described above; wherein, in combination with the insertion pipe 30 protruding from the main unit 10 and the sleeve 50 being provided in the water tank 20 and inside the water tank 20, the second seal 61 in the embodiments of the present utility model is in sealing connection with one end of the sleeve 50 inside the water tank 20, and the second piston rod 62 moves towards the inside of the water tank 20 after being mutually pressed with the first piston rod 42.

[0055] Please refer to Figure 5 and Figure 6 As shown, in some embodiments of the present utility model, the sleeve 50 includes a second pipe body portion 51 and a second limiting portion 52. The second pipe body portion 51 is connected to the main unit 10 or the water tank 20, and the second seal 61 is in sealing contact with the second pipe body portion 51; the second limiting portion 52 is inside the second pipe body portion 51 and protrudes from the inner pipe wall of the second pipe body portion 51, and the first elastic member 43 is clamped between the first limiting portion 32 and the end of the first piston rod 42 away from the first seal 41.

[0056] After the second elastic member 63 is clamped between the second limiting portion 52 and the end of the second piston rod 62 away from the second seal member 61, the second elastic member 63 causes the second piston rod 62 to tend to move towards the insertion pipe 30. However, the second limiting portion 52 is clamped between the second elastic member 63 and the second seal member 61, and the second seal member 61 restricts the second piston rod 62 from moving towards the sleeve 50. At this time, the force on the second piston rod 62 reaches equilibrium, and it can only move away from the water tank 20 when acted upon by an external force, realizing the fixation of the second seal assembly 60 within the sleeve 50, and the second seal member 61 is tightly connected to the second pipe body portion 51 under the action of the second elastic member 63.

[0057] Among them, the second open state means that the second seal member 61 is completely separated from the second pipe body portion 51.

[0058] Please refer to Figure 5 and Figure 6 As shown, in some embodiments of the present utility model, the pipeline drinking water device further includes a third seal member 70. The third seal member 70 is located within the second pipe body portion 51 and is in sealing contact with the inner pipe wall of the second pipe body portion 51. When at least a part of the insertion pipe 30 is inserted into the sleeve 50, the third seal member 70 is in sealing contact with the outer pipe wall of the first pipe body portion 31.

[0059] When at least a part of the insertion pipe 30 is within the sleeve 50, the third seal member 70 is in sealing connection with the outer pipe wall of the first pipe body portion 31 and in sealing connection with the inner pipe wall of the second pipe body portion 51, ensuring the sealing connection between the insertion pipe 30 and the sleeve 50 when the water tank 20 and the main unit 10 are interconnected. The third seal member 70 in the embodiments of the present utility model can be configured as a sealing sleeve.

[0060] Please refer to Figure 1 and Figure 2 As shown, in some embodiments of the present utility model, the water tank 20 includes a main body portion 21 and a handle portion 22 that are interconnected. A receiving cavity is recessed on the side of the main body portion 21 away from the main unit 10. The handle portion 22 is within the receiving cavity and only occupies a part of the space in the receiving cavity, facilitating the user to separate the water tank 20 from the main unit 10.

[0061] In the embodiments of the present utility model, the main body portion 21 and the handle portion 22 are integrally provided. Both the main body portion 21 and the handle portion 22 are hollow and interconnected to increase the volume of the water tank 20.

[0062] In some embodiments of the present utility model, the pipeline drinking water device further includes a detection circuit and a trigger member.

[0063] The detection circuit includes a detection component and an indicator light. Both the detection component and the indicator light are fixed to one of the main unit 10 and the water tank 20; the actuating component is fixed to the other of the main unit 10 and the water tank 20. After the actuating component touches the detection component, the detection circuit is turned on. After the actuating component triggers the detection component, the detection circuit is turned on, and the indicator light emits light to indicate that the water tank 20 and the main unit 10 are connected to each other.

[0064] Since the main unit 10 needs to pump the water in the water tank 20 and then heat or cool it, the main unit 10 must be powered on. Therefore, in some embodiments of the present invention, the detection circuit is fixed to the main unit 10, the detection component is configured as a reed switch, the actuating component is fixed to the water tank 20, and is configured as a magnetic component; when the reed switch is subjected to a magnetic force, two magnetic reed pieces in the reed switch contact each other under the action of the magnetic force, turning on the detection circuit, and then causing the indicator light to emit light.

[0065] The magnetic component in the embodiments of the present invention can be configured as a permanent magnet, and only needs to be installed on the water tank 20 or the main unit 10; of course, the magnetic component in the embodiments of the present invention can also be configured as an electromagnet.

[0066] A reed switch is a special magnetic-sensitive switch. Its basic form is to seal two magnetic reed pieces in a glass tube. Although the two overlap, there is a small gap in the middle. When an external magnetic field approaches, the external magnetic field exerts a force on the two magnetic reed pieces to make the two magnetic reed pieces contact each other, thereby turning on the reed switch. The reed switch has a simpler structure, smaller volume, higher speed, and longer working life than a general mechanical switch; compared with an electronic switch, it also has the characteristics of strong anti-load impact ability and high working reliability.

[0067] The indicator light is used to indicate whether the water tank 20 is installed in place. In the embodiments of the present invention, the indicator light can be configured as an LED (light-emitting diode) lamp. The light emitted by the LED lamp has strong penetration, and the LED lamp can emit various colors of light to indicate whether the water tank 20 is installed in place.

[0068] In some embodiments of the present invention, the actuating component is located on the side of the water tank 20 close to the main unit 10, the detection component is located on the side of the main unit 10 close to the water tank 20, and the actuating component is arranged opposite to the detection component.
