Description

Technical Field

[0001] This application relates to the field of liquid storage container technology, and in particular to a liquid storage tank and cleaning device. Background Technology

[0002] Cleaning devices typically include a storage tank and a heating device, which heats the liquid inside the storage tank. In related technologies, there are generally two heating methods for the heating device: one is to place the heating device directly inside the storage tank to heat the liquid, and the other is to allow the liquid in the storage tank to flow into the heating device for heating.

[0003] The inventors of this application have discovered that when a liquid storage tank is drained, liquid tends to remain at the bottom of the tank, which can easily lead to incomplete liquid drainage. Utility Model Content

[0004] In view of the above problems, this application provides a liquid storage tank and a cleaning device, which overcomes or at least partially solves the above problems.

[0005] According to one aspect of this application, a liquid storage tank is provided, including a tank body, a liquid storage cavity and an opening communicating with the liquid storage cavity, and a mounting hole. The mounting hole is disposed in the tank body and located at the bottom of the liquid storage cavity. The mounting hole communicates with the liquid storage cavity. The mounting hole and the opening are disposed opposite to each other, and liquid can flow into or out of the liquid storage cavity from the mounting hole.

[0006] In one alternative embodiment, the liquid storage tank further includes a control valve disposed in the mounting hole, the control valve being capable of adjusting the liquid flow rate through the mounting hole.

[0007] In one alternative embodiment, the mounting hole includes a first mounting hole and a second mounting hole, both of which are located at the bottom of the liquid storage chamber and are spaced apart from each other. The number of control valves is at least one, and the control valves are disposed in the first mounting hole and / or the second mounting hole.

[0008] In one alternative embodiment, the liquid storage tank further includes a tank frame connected to the side of the tank body away from the bottom of the liquid storage cavity. The tank body is foldable, either folding towards the tank frame or unfolding away from the tank frame. The inner diameter of the tank frame is larger than the outer diameter of the tank body, and when the tank body is folded, at least a portion of the tank body is located within the tank frame.

[0009] In one alternative embodiment, the liquid storage tank further includes a handle rotatably connected to the tank frame, the outer periphery of which has a mounting groove, and at least a portion of the handle is located within the mounting groove.

[0010] In one alternative embodiment, the bottom of the liquid storage cavity extends with a first protrusion and a second protrusion, the first protrusion and the second protrusion being spaced apart, the first mounting hole being located on the first protrusion, and the second mounting hole being located on the second protrusion.

[0011] According to one aspect of this application, a cleaning apparatus is provided, including a liquid heating device and a liquid storage tank as described above, wherein a mounting hole of the liquid storage tank communicates with the interior of the liquid heating device, and liquid in the liquid storage tank flows into the liquid heating device through the mounting hole, and the liquid heating device can be used to heat the liquid flowing into it.

[0012] According to one aspect of this application, a cleaning device is provided, including a liquid heating device and a liquid storage tank as described above. The first mounting hole and the second mounting hole of the liquid storage tank are both in communication with the interior of the liquid heating device. Liquid in the liquid storage tank flows into the liquid heating device from the first mounting hole, and after being heated by the liquid heating device, the liquid flows back into the liquid storage tank from the second mounting hole.

[0013] In one optional embodiment, the liquid heating device includes a housing, a liquid pump, a piping assembly, and a heating assembly. The housing has a liquid inlet, a first liquid outlet, and a second liquid outlet. The liquid pump is disposed within the housing, with its inlet connected to the liquid inlet. The piping assembly is disposed within the housing, with one end connected to the liquid outlet of the liquid pump and the other end connected to both the first and second liquid outlets. The heating assembly is disposed within the housing and connected to the liquid outlet of the liquid pump, located between the liquid pump and the piping assembly. A first mounting hole is connected to the liquid inlet, and a second mounting hole is connected to the first liquid outlet. Liquid in the storage tank can flow from the first mounting hole through the liquid pump, the heating assembly, and the piping assembly, and then flow back to the storage tank from the second mounting hole.

[0014] In one alternative embodiment, a limiting groove is provided at one end of the housing near the liquid storage tank; a limiting protrusion is provided at one end of the liquid storage tank near the housing, and the limiting protrusion is engaged within the limiting groove.

[0015] The beneficial effects of this application embodiment are as follows: Unlike the prior art, this application embodiment includes a barrel body and a mounting hole. The barrel body has a liquid storage chamber and an opening communicating with the liquid storage chamber. The mounting hole is located inside the barrel body at the bottom of the liquid storage chamber and communicates with it. The mounting hole and the opening are positioned opposite each other, allowing liquid to flow into or out of the liquid storage chamber through the mounting hole. This configuration ensures that when the liquid storage barrel is drained, the liquid can flow out through the mounting hole. Since the mounting hole is located at the bottom of the liquid storage chamber, liquid residue at the bottom of the chamber is reduced, thus minimizing the problem of incomplete liquid drainage.

The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the scope of this application. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0020] Furthermore, the technical features involved in the different embodiments of this application described below can be combined with each other as long as they do not conflict with each other.

[0021] It should be noted that: In this application, the liquid storage tank is used as an example for the cleaning device. In this case, the liquid in the liquid storage tank is water. It can be understood that in other embodiments, the liquid in the liquid storage tank includes, but is not limited to, water, aqueous solution, beverage, chemical solvent or other heatable liquid.

[0022] Please see Figure 1 and Figure 2 The cleaning device 1000 includes a liquid storage tank 10, a flushing assembly 20, and a liquid heating device 30. The liquid storage tank 10 is connected to the liquid heating device 30. Liquid in the liquid storage tank 10 can flow into the liquid heating device 30 for heating and then flow back into the liquid storage tank 10. The flushing assembly 20 is connected to the liquid heating device 30, and liquid heated by the liquid heating device 30 can flow out from the flushing assembly 20. The liquid storage tank 10, the flushing assembly 20, and the liquid heating device 30 are described in detail below.

[0023] For the aforementioned storage tank 10, as Figures 3-5As shown, the liquid storage tank 10 is provided with a liquid storage cavity 10a and an opening 10aa communicating with the liquid storage cavity 10a. The liquid storage tank 10 is also provided with an installation hole 10b communicating with the liquid storage cavity 10a. The installation hole 10b is located inside the liquid storage tank 10 and is located at the bottom of the liquid storage cavity 10a. The installation hole 10b is opposite to the opening 10aa, and liquid can flow into or out of the liquid storage cavity 10a from the installation hole 10b.

[0024] In some embodiments, the mounting hole 10b includes a first mounting hole 10b1 and a second mounting hole 10b2, which are spaced apart at the bottom of the liquid storage chamber 10a. The first mounting hole 10b1 and the second mounting hole 10b2 can be used to connect the liquid heating device 30, wherein the liquid in the liquid storage chamber 10a can flow into the liquid heating device 30 from the first mounting hole 10b1 and flow back into the liquid storage chamber 10a from the second mounting hole 10b2.

[0025] In some embodiments, the liquid storage tank 10 includes a tank frame 11 and a tank body 12. The tank frame 11 is connected to the tank body 12, and the tank body 12 is foldable. Thus, the liquid storage tank 10 can be in a first state and a second state. When the liquid storage tank 10 is in the first state, the tank body 12 is folded and unfolded. At this time, the liquid storage tank 10 can hold more liquid for users to take long showers. When the liquid storage tank 10 is in the second state, the tank body 12 is folded and stored. At this time, the external space occupied by the liquid storage tank 10 in the vertical direction can be reduced, and the storage and transportation of the liquid storage tank 10 can be facilitated.

[0026] In some embodiments, the barrel 12 includes a soft rubber inner shell 121 and a bottom shell 122 connected to the soft rubber inner shell 121. The first mounting hole 10b1 and the second mounting hole 10b2 are both located on the bottom shell 122. The soft rubber inner shell 121 is foldable, thereby allowing the liquid storage tank 10 to change between a first state and a second state.

[0027] In some embodiments, the inner diameter of the barrel frame 11 is larger than the inner diameter of the barrel body 12, and when the liquid storage barrel 10 is in the second state, at least a portion of the barrel body 12 is housed within the barrel frame 11.

[0028] In some embodiments, the liquid storage tank 10 further includes a control valve 13 disposed in the mounting hole 10b, and the control valve 13 can adjust the liquid flow rate through the mounting hole 10b.

[0029] In some embodiments, the number of control valves 13 is at least one, and the control valves 13 are disposed in the first mounting hole 10b1 and / or the second mounting hole 10b2. Specifically, when there is only one control valve 13, it may be disposed in either the first mounting hole 10b1 or the second mounting hole 10b2; when there are two control valves 13, one control valve 13 is disposed in the first mounting hole 10b1 and the other control valve 13 is disposed in the second mounting hole 10b2.

[0030] In some embodiments, the control valve 13 includes a first valve 131 disposed in the first mounting hole 10b1, and liquid in the liquid storage chamber 10a can flow out of or into the liquid storage chamber 10a from the first mounting hole 10b1 through the first valve 131. In some embodiments, the first valve 131 is a one-way valve, and the liquid in the storage chamber 10a can flow out unidirectionally from the first mounting hole 10b1 through the first valve 131. The user can connect the first mounting hole 10b1 on the barrel 12 with the pipeline of the heating device 30, and the liquid in the barrel 12 can flow into the pipeline of the heating device 30 through the first mounting hole 10b1 for heating. When the pump in the heating device 30 stops running, since the first valve 131 provided in the first mounting hole 10b1 is a one-way valve, the one-way valve can only allow the liquid in the storage chamber 10a to flow out unidirectionally from the first mounting hole 10b1. At this time, the first valve 131 can prevent the liquid in the pipeline of the heating device 30 from flowing back into the storage tank 10, thereby reducing the cross-contamination between the liquid in the pipeline and the liquid in the storage tank 10.

[0031] In some embodiments, the control valve 13 further includes a second valve 132, which is disposed in the second mounting hole 10b2. The second valve 132 allows liquid to flow into or out of the storage chamber 10a in one direction from the second mounting hole 10b2. When the user uses the storage tank 10 to store water, the action of the first valve 131 and the second valve 132 can reduce the leakage of water from the storage tank 10. When the storage tank 10 is connected to the liquid heating device 30, the first valve 131 and the second valve 132 can ensure that the liquid in the storage tank 10 can flow normally into the liquid heating device 30. It should be noted that the liquid flow direction in the first valve 131 and the second valve 132 can be the same or opposite. For example, the first valve 131 and the second valve 132 can both be outlet valves to ensure that the liquid in the storage tank 10 can flow normally into the liquid heating device 30. The liquid flow direction in the first valve 131 and the second valve 132 is opposite. The first valve 131 is the outlet valve and the second valve 132 is the inlet valve. The liquid in the storage tank 10 can flow into the liquid heating device 30 in one direction from the first valve 131. The liquid heated by the liquid heating device 30 can flow back into the storage tank 10 in one direction from the second valve 132.

[0032] In some embodiments, the liquid storage tank 10 is also provided with a handle 14, which is rotatably disposed on the tank frame 11. The handle 14 can rotate relative to the tank frame 11 by a preset angle, and the handle 14 is located on the outer periphery of the tank frame 11 in the initial state.

[0033] In some embodiments, the outer periphery of the barrel frame 11 is recessed with a mounting groove 111, and at least a portion of the handle 14 is located in the mounting groove 111. The mounting groove 111 can store the handle 14, reducing the direct exposure of the handle 14 to the outer wall of the barrel frame 11 and reducing contact and friction between the handle 14 and surrounding objects.

[0034] In some embodiments, the bottom of the liquid storage chamber 10a extends with a first protrusion 12a and a second protrusion 12b, which are spaced apart. A first mounting hole 10b1 is located on the first protrusion 12a, and a second mounting hole 10b2 is located on the second protrusion 12b. The arrangement of the first protrusion 12a and the second protrusion 12b can reduce the outflow of impurities from the bottom of the liquid storage chamber 10a through the first mounting hole 10b1 and the second mounting hole 10b2.

[0035] For the above-mentioned liquid heating device 30, such as Figures 6-8 As shown, the liquid heating device 30 can be used to heat the liquid in the storage tank 10. The liquid heating device 30 includes a housing 31, a liquid pump 32, a pipeline assembly 33, and a heating assembly 34. The housing 31 is provided with a receiving cavity 31a and a liquid inlet 31b, a first liquid outlet 31c, and a second liquid outlet 31d communicating with the receiving cavity 31a. The liquid pump 32, the pipeline assembly 33, and the heating assembly 34 are all disposed inside the housing 31. The liquid inlet of the liquid pump 32 is connected to the liquid inlet 31b on the housing 31. One end of the pipeline assembly 33 is connected to the liquid outlet of the liquid pump 32, and the other end of the pipeline assembly 33 is connected to the first liquid outlet 31c and the second liquid outlet 31d. The heating assembly 34 is connected to the liquid outlet of the liquid pump 32 and is located between the liquid pump 32 and the pipeline assembly 33. The first liquid outlet 31c is a circulating liquid outlet so that the liquid in the storage tank 10 flows from the liquid inlet 31b. The liquid flows through the pump 32, heating element 34, and piping assembly 33, and exits from the first outlet 31c into the storage tank 10 to form a circulation. When the user needs to take an outdoor shower, the storage tank 10 can be connected to the inlet 31b and the first outlet 31c on the liquid heating device 30. The cold water in the storage tank 10 can enter from the inlet 31b and flow through the pump 32, heating element 34, and piping assembly 33, exiting from the first outlet 31c into the storage tank 10, thus preheating the water in the storage tank 10. The preheated water can then enter again from the inlet 31b, and so on, completing the cycle. After two or more heating cycles, hot water can flow out from the shower head 202 at the second outlet 31d for the user to use outdoors, thereby achieving a stable water temperature in the outdoor environment and improving the user's showering experience.

[0036] In some embodiments, a mounting bracket 311 is also provided inside the housing 31. The mounting bracket 311 is located inside the receiving cavity 31a and is fixed relative to the housing 31. The pipeline assembly 33 and the heating assembly 34 are both limited and fixed on the mounting bracket 311.

[0037] In some embodiments, the bottom plate of the housing 31 is also provided with a foot pad 312. The foot pad 312 is detachably connected to the housing 31. The foot pad 312 can play a shock absorption and cushioning role, and at the same time, it can reduce the wear caused by the direct contact and friction between the housing 31 and the ground.

[0038] In some embodiments, please refer to the following: Figure 3 and Figure 7 A limiting groove 313 is provided at one end of the housing 31 near the liquid storage tank 10, and a limiting protrusion 12c is provided at one end of the liquid storage tank 10 near the housing 31. The limiting protrusion 12c is engaged in the limiting groove 313, thereby ensuring that the liquid storage tank 10 can be stably connected to the housing 31 of the liquid heating device 30.

[0039] In some embodiments, please refer to the following: Figure 8 and Figure 9 The liquid heating device 30 also includes a grounding member 35, which is used for grounding. The grounding member 35 is connected to the outlet of the liquid pump 32 and is located between the heating assembly 34 and the liquid pump 32. At least a portion of the liquid flowing from the outlet of the liquid pump 32 toward the heating assembly 34 flows through the grounding member 35. The grounding member 35 can provide leakage protection, reducing the possibility of electric shock to users who come into contact with the heating assembly 34, the liquid pump 32, or the liquid. It should be noted that the power port 314 of the liquid heating device 30 is usually installed on the housing 31 and is connected to the control board assembly 36 of the liquid heating device 30. To ground the grounding member 35, the grounding member 35 is connected to the grounding terminal in the power port 314 via a wire. In some embodiments, the grounding member 35 is detachably connected to the outlet of the liquid pump 32 and is located at the connection between the heating assembly 34 and the liquid pump 32.

[0040] In some embodiments, a portion of the grounding member 35 is located within the heating assembly 34, and at least a portion of the liquid flowing from the outlet of the self-liquid pump 32 toward the heating assembly 34 flows through the grounding member 35, which can serve as a leakage protection device.

[0041] In some embodiments, the grounding member 35 includes a fixing plate 351 and a hollow column 352 extending from the fixing plate 351. The fixing plate 351 is detachably connected to the liquid pump 32. The inner wall of the hollow column 352 is fitted into the liquid outlet of the liquid pump 32, and the outer wall of the hollow column 352 is inserted into the heating tube 341 of the heating assembly 34. The fixing plate 351 is used to connect to the liquid pump 32 to fix the grounding member 35 relative to the liquid pump 32. The inner wall of the hollow column 352 connects to the liquid outlet of the liquid pump 32 to form a first sealing structure, and the outer wall of the hollow column 352 connects to the heating tube 341 to form a second sealing structure. This arrangement reduces liquid leakage. As the liquid in the storage tank 10 flows from the liquid outlet of the liquid pump 32 to the heating assembly 34, it flows through the hollow column 352 of the grounding member 35. The grounding member 35 can conduct the leakage current from the heating assembly 34, the liquid pump 32, and the liquid to the ground, reducing the risk of electric shock.

[0042] In some embodiments, one end of the fixing plate 351 is bent and extends to form a connecting plate 353. The connecting plate 353 has a plurality of grounding connection points 353a, which are spaced apart. One of the grounding connection points 353a can be connected to a component in the control board assembly 36 via a wire to conduct leakage current from the control board assembly 36 to the ground. It is understood that each grounding connection point 353a can be used to connect different electronic devices to conduct leakage current from the electronic devices to the ground, reducing the risk of electric shock.

[0043] In some embodiments, please refer to the following: Figure 8 and Figure 10 The liquid heating device 30 also includes a control board assembly 36, which is electrically connected to the liquid pump 32 and the heating assembly 34. The control board assembly 36 is rotatably connected to the first pipe 331 of the pipe assembly 33. The control board assembly 36 can rotate a preset angle relative to the axis of the first pipe 331. The control board assembly 36 can be used to control the liquid pump 32 and the heating assembly 34. During the installation or maintenance of the electronic components in the control board assembly 36, the user can rotate the control board assembly 36 to a preset angle for easier installation or maintenance. Compared to the control board assembly 36 in related technologies that is fixed to the housing 31 with screws, the installation and maintenance of the control board assembly 36 in this application is more convenient. It is understood that the rotation angle of the control board assembly 36 is not specifically limited in this application; for example, it can be 45 degrees, 90 degrees, 180 degrees, etc.

[0044] In some embodiments, the liquid heating device 30 further includes a keypad 37 disposed on the outer wall of the housing 31. The keypad 37 is electrically connected to the control board assembly 36 and can be used to control the control board assembly 36.

[0045] In some embodiments, please refer to the following: Figure 8 and Figure 11 The piping assembly 33 includes a first pipe 331, a second pipe 332, a third pipe 333, and a three-way pipe 334. One end of the first pipe 331 is connected to the heating assembly 34, and the other end of the first pipe 331 is connected to the three-way pipe 334. One end of the second pipe 332 is connected to the three-way pipe 334, and the other end of the second pipe 332 is connected to the first liquid outlet 31c. One end of the third pipe 333 is connected to the three-way pipe 334, and the other end of the third pipe 333 is connected to the second liquid outlet 31d. The liquid in the storage tank 10 flows from the outlet of the self-liquid pump 32 to the heating assembly 34. After being heated by the heating component 34, the liquid flows into the first pipe 331. When the liquid flows through the three-way pipe 334, part of the liquid flows to the second pipe 332 and flows out from the first liquid outlet 31c, while the other part of the liquid flows to the third pipe 333 and flows out from the second liquid outlet 31d. This arrangement allows one heating point to supply liquid to two usage points simultaneously, saving costs and space. The two liquids are mixed in front of the same three-way pipe 334, resulting in uniform temperature and preventing one from being overheated and the other from being undercooled, thus reducing the possibility of large temperature differences between the two liquids.

[0046] In some embodiments, the liquid heating device 30 includes an electronic valve 38 disposed on the second pipe 332. The electronic valve 38 can instantaneously, precisely, and programmably adjust the on / off state and flow rate of the second pipe 332 via an electrical signal. It is understood that since the liquid in both the second pipe 332 and the third pipe 333 originates from the first pipe 331, when the liquid flow rate in the second pipe 332 is adjusted by the electronic valve 38, the liquid flow rate in the third pipe 333 will typically also change. For example, when the liquid flow rate in the second pipe 332 increases, the liquid flow rate in the third pipe 333 decreases; conversely, when the liquid flow rate in the second pipe 332 decreases, the liquid flow rate in the third pipe 333 increases.

[0047] In some embodiments, the liquid heating device 30 includes a flow meter 39, which is disposed on a third pipeline 333 and can monitor and measure the amount of liquid flow in the third pipeline 333.

[0048] In some embodiments, please refer to the following: Figure 12 and Figure 13The heating assembly 34 includes a heating tube 341, a heating body 342, and a flow-deflecting element 343. One end of the heating tube 341 is connected to the outlet of the liquid pump 32, and the other end of the heating tube 341 is connected to the pipeline assembly 33. The heating body 342 is located inside the heating tube 341, and the flow-deflecting element 343 is arranged around the heating body 342. A liquid flow gap 34a is spaced between the outer wall of the heating body 342 and the inner wall of the heating tube 341. At least part of the liquid flowing out of the outlet of the liquid pump 32 flows from the liquid flow gap 34a to the pipeline assembly 33. It should be noted that during the heating process, heat is transferred from the heating element 342 to the liquid. Without the flow-deflecting element 343, the liquid flow may be relatively slow, easily leading to uneven heat transfer. In this application, by providing the flow-deflecting element 343, the flow state of the liquid can be changed, thereby generating turbulence around the heating element 342, increasing the contact area and contact frequency between the liquid and the heating element 342, thus improving the efficiency of heat transfer and allowing the liquid to reach the required temperature more quickly. When the liquid flows through the liquid flow gap 34a, it contacts the outer wall of the heating element 342 to achieve heating. In some embodiments, the heating element 342 can be a ceramic heater, a PTC heater, an electric heating wire heater, etc. In some embodiments, the flow-deflecting element 343 is spiral-shaped.

[0049] In some embodiments, the heating body 342 is provided with a heating cavity 342a and a first liquid flow hole 342b and a second liquid flow hole 342c communicating with the heating cavity 342a. The first liquid flow hole 342b is disposed opposite to the outlet of the liquid pump 32, and the second liquid flow hole 342c is located at one end of the heating body 342 near the pipeline assembly 33. Part of the liquid flowing out of the outlet flows through the heating cavity 342a from the first liquid flow hole 342b and flows to the pipeline assembly 33 from the second liquid flow hole 342c. When a part of the liquid to be heated flows through the heating cavity 342a, it can contact the inner wall of the heating body 342 to achieve heating.

[0050] In some embodiments, the heating assembly 34 further includes a flow guide 344, which is installed in the second liquid flow hole 342c. A flow guide gap 34b is provided between the flow guide 344 and the inner wall of the heating cavity 342a. Liquid flowing through the heating cavity 342a can at least partially flow from the flow guide gap 34b to the pipeline assembly 33. Under the action of the flow guide 344, the liquid to be heated flows from the flow guide gap 34b to the second liquid flow hole 342c. The flow guide gap 34b can increase the contact area between the liquid to be heated and the inner wall of the heating body 342, thereby increasing the contact area between the liquid to be heated and the heating body 342, and thus improving the heating efficiency of the heating assembly 34.

[0051] In some embodiments, please refer to the following: Figure 13 and Figure 14The flow guide 344 includes a flow guide cone 3441 and multiple locking blocks 3442 located on the outer wall of the flow guide cone 3441. The multiple locking blocks 3442 are arranged around and spaced apart on the outer wall of the flow guide cone 3441. The flow guide cone 3441 is separated from the inner wall of the heating cavity 342a by a flow guide gap 34b. The locking blocks 3442 are used to engage with the inner wall of the heating cavity 342a. The flow guide 344 can be engaged with the inner wall of the heating cavity 342a by the locking blocks 3442, thereby realizing the stable connection of the flow guide 344 to the heating body 342. The flow guide cone 3441 can guide the liquid flowing through the heating cavity 342a.

[0052] In some embodiments, the guide cone 3441 includes a first inclined portion 3441a, a horizontal portion 3441b, and a second inclined portion 3441c connected in sequence. The second inclined portion 3441c is disposed closer to the second liquid flow hole 342c than the first inclined portion 3441a. Along the direction from the first inclined portion 3441a toward the horizontal portion 3441b, the outer diameter of the first inclined portion 3441a gradually increases, and the outer diameter of the second inclined portion 3441c gradually decreases. The first inclined portion 3441a can guide the liquid to the aforementioned guide gap 34b, and the second inclined portion 3441c can guide the liquid flowing out of the guide gap 34b to the second liquid flow hole 342c and flow to the pipeline assembly 33.

[0053] In some embodiments, the flow guide 344 further includes a first flow guide column 3443, which is connected to one end of the flow guide cone 3441 near the first liquid flow hole 342b. The outer diameter of the first flow guide column 3443 gradually increases along the direction from the first liquid flow hole 342b toward the second liquid flow hole 342c. The first flow guide column 3443 can guide the liquid located in the heating cavity 342a and can guide the liquid toward the direction of the flow guide cone 3441.

[0054] In some embodiments, the guide member 344 is provided with a buffer cavity 344a that communicates with the heating cavity 342a. During the process of the liquid to be heated flowing into the heating cavity 342a from the first liquid flow hole 342b and flowing out from the second liquid flow hole 342c, part of the liquid to be heated flows into the buffer cavity 344a. The buffer cavity 344a can buffer the liquid to be heated flowing towards the second liquid flow hole 342c, so as to stabilize the flow rate of the liquid to be heated in the heating cavity 342a and reduce the impact of the liquid to be heated.

[0055] In some embodiments, the flow guide 344 further includes a second flow guide column 3444, which is connected to one end of the flow guide cone 3441 near the second liquid flow hole 342c. The outer diameter of the second flow guide column 3444 gradually decreases along the direction from the first liquid flow hole 342b toward the second liquid flow hole 342c. The second flow guide column 3444 can guide the liquid flowing out of the second liquid flow hole 342c to the conduit assembly 33.

[0056] In some embodiments, the heating tube 341 is provided with a liquid flow space 341a and an inlet channel 341b and an outlet channel 341c communicating with the liquid flow space 341a. The heating element 342 is located in the liquid flow space 341a. The liquid to be heated can enter the liquid flow space 341a from the inlet channel 341b, flow through the heating element 342 and flow out from the outlet channel 341c. The heating assembly 34 also includes a first temperature sensor 345 and a second temperature sensor 346. Both the first temperature sensor 345 and the second temperature sensor 346 are disposed on the heating tube 341. A portion of the first temperature sensor 345 is located in the inlet channel 341b, and a portion of the second temperature sensor 346 is located in the outlet channel 341c. The first temperature sensor 345 is used to detect the temperature of the liquid in the inlet channel 341b, and the second temperature sensor 346 is used to detect the temperature of the liquid in the outlet channel 341c. In some embodiments, the inlet channel 341b is connected to the outlet of the liquid pump 32, and the outlet channel 341c is connected to the pipeline assembly 33.

[0057] In some embodiments, the heating assembly 34 further includes a third temperature sensor 347, which is disposed on the heating tube 341 and a portion of the third temperature sensor 347 is located within the liquid flow space 341a. The third temperature sensor 347 is used to detect the temperature of the liquid within the liquid flow space 341a.

[0058] In some embodiments, along the radial direction of the heating body 342, the first liquid flow hole 342b and the liquid inlet channel 341b are at least partially opposite to each other. After the liquid to be heated flows out from the liquid inlet channel 341b, it can directly flow through the first liquid flow hole 342b into the heating cavity 342a for heating, thereby improving the heating efficiency of the liquid to be heated.

[0059] For the aforementioned flushing component 20, such as Figure 1 As shown, the flushing assembly 20 is connected to the second liquid outlet 31d on the liquid heating device 30. Liquid heated by the liquid heating device 30 can flow out of the flushing assembly 20 for the user to shower. In some embodiments, the flushing assembly 20 includes a hose 201 and a shower head 202 connected to the hose 201. One end of the hose 201 away from the shower head 202 is connected to the second liquid outlet 31d. Liquid flowing out of the second liquid outlet 31d can flow through the hose 201 and out of the shower head 202.

[0060] In this embodiment, a barrel body 12 and a mounting hole 10b are provided. The barrel body 12 has a liquid storage chamber 10a and an opening 10aa communicating with the liquid storage chamber 10a. The mounting hole 10b is located inside the barrel body at the bottom of the liquid storage chamber 10a and communicates with it. The mounting hole 10b and the opening 10aa are positioned opposite each other, allowing liquid to flow into or out of the liquid storage chamber 10a through the mounting hole 10b. This configuration ensures that when the barrel is drained, the liquid can flow out through the mounting hole 10b. Since the mounting hole 10b is located at the bottom of the liquid storage chamber 10a, liquid residue at the bottom of the liquid storage chamber 10a is reduced, thus minimizing the problem of incomplete liquid drainage.
