Description

Technical Field

[0001] This utility model relates to the field of electrical appliances, and in particular to a cleaning device. Background Technology

[0002] In existing cleaning equipment such as vacuum cleaners, fluids (cold water, hot water, steam) are sprayed onto the roller brush to enhance the cleaning effect, thus assisting the roller brush in cleaning dirt on floors, walls, and other surfaces.

[0003] In existing cleaning equipment, the heater used to heat cold water is controlled by a separate control device. The user needs to actively control the heater through the control device, which cannot be linked with the control of the valve device. This increases the complexity of the cleaning equipment control and makes it impossible to flexibly deliver the required fluids (cold water, hot water, steam) to the roller brush, resulting in a poor user experience. Utility Model Content

[0004] This utility model provides a cleaning device, the purpose of which is to solve the problems of complex control and poor user experience of existing cleaning devices.

[0005] To achieve the above objectives, this utility model provides a cleaning device, comprising: spray nozzle; A heater, the outlet of which is in fluid communication with the nozzle; The cleaning equipment also includes: A valve device, the valve device including a valve body and a valve core assembly disposed in the valve body, the valve body having an inlet and multiple outlets, the multiple outlets including a first outlet, the first outlet being in fluid communication with the inlet of the heater; A driving component, which controls the rotation of the valve core assembly by electric or mechanical drive to adjust the connection between the inlet and the plurality of outlets; A detection element is provided, which outputs an electrical signal to a control circuit when the drive element or the valve core assembly moves to a specific position; the specific position is defined as the position of the drive element or the valve core assembly when the inlet is connected to the first outlet. The heater is electrically connected to the control circuit.

[0006] With the above configuration, when the drive component or valve core assembly moves to a specific position that allows the inlet and the first outlet to connect, the detection element outputs an electrical signal to the control circuit. Upon receiving the signal, the control circuit can control the heater to start, enabling it to heat the cold water entering the heater. The heater can automatically start when needed, eliminating the need for manual control by the user. This simplifies and enhances the user experience by making the cleaning equipment easy to control.

[0007] As a further improvement of this utility model, the cleaning device is configured to control the rotation of the valve core assembly by rotating the drive component; The detection element is a micro switch, which is disposed near the driving component. The sensing end of the micro switch is fixedly disposed on the rotation path of the driving component, and the sensing end of the micro switch faces the circumferential surface of the driving component. The driving component is provided with a trigger part, which is disposed on the circumferential surface of the driving component; when the driving component rotates to the specific position, the trigger part interferes with the sensing end to trigger the micro switch to output the electrical signal.

[0008] When the drive component rotates to a specific position, the micro switch can be accurately triggered to output an electrical signal. The control circuit can accurately determine whether the drive component is in a specific position through the micro switch, thereby deciding whether to control the heater to start.

[0009] As a further improvement of this utility model, the micro switch includes a first micro switch and a second micro switch; the specific position includes a first rotation position and a second rotation position; When the driving component rotates to the first rotation position, the triggering part interferes with the sensing end of the first micro switch to trigger the first micro switch to output an electrical signal to the control circuit. When the drive unit rotates to the second rotation position, the triggering part interferes with the sensing ends of the first micro switch and the second micro switch, thereby triggering both the first micro switch and the second micro switch to output electrical signals to the control circuit.

[0010] When the driving component rotates to the first rotation position, only the first micro switch outputs an electrical signal to the control circuit. When the driving component rotates to the second rotation position, both the first and second micro switches output electrical signals to the control circuit. The control circuit can accurately determine whether the driving component is in the first or second rotation position based on the received electrical signals.

[0011] As a further improvement of this utility model, when the driving member rotates to the first rotation position, the maximum flow rate between the inlet and the first outlet is the first flow rate, and the fluid output temperature of the heater is the first temperature; When the drive unit rotates to the second rotation position, the maximum flow rate between the inlet and the first outlet is the second flow rate, and the fluid output temperature of the heater is the second temperature, wherein the first flow rate is greater than the second flow rate, and the first temperature is less than the second temperature.

[0012] The above configuration controls the maximum flow rate between the inlet and the first outlet and the fluid output temperature of the heater when the drive unit is in the first and second rotation positions, respectively. This allows the heater to produce hot water and steam, both of which can flow to the nozzle and be sprayed onto the roller brush, thus meeting the working needs of the cleaning equipment.

[0013] As a further improvement of this utility model, the plurality of outlets further includes a second outlet in fluid communication with the nozzle, the cleaning device further includes a mixing chamber, the inlet of the mixing chamber is connected to the outlet of the heater and the second outlet respectively, and the outlet of the mixing chamber is connected to the nozzle; the specific position includes a first rotation position and a second rotation position; When the drive unit rotates to the first rotation position, the inlet simultaneously connects to the first outlet and the second outlet, and the triggering part interferes with the sensing end of the micro switch; When the drive unit rotates to the second rotation position, the inlet is connected only to the first outlet, and the triggering part interferes with the sensing end of the micro switch.

[0014] Thus, when the drive unit rotates to the first rotation position, the cold water entering the valve body from the inlet can flow out in two separate streams from the first outlet and the second outlet. One stream of cold water flows through the first outlet to the heater, where it is heated into hot water and then flows into the mixing chamber. The other stream of cold water flows directly into the mixing chamber through the second outlet. After the cold and hot water mix in the mixing chamber, they flow to the nozzle, which then sprays out warm water.

[0015] When the drive unit rotates to the second rotation position, the inlet is connected to the first outlet only. The cold water entering the valve body from the inlet will only flow to the heater through the first outlet. The heater can heat the cold water into high-temperature water vapor, and the water vapor will then flow to the nozzle, which can spray out high-temperature water vapor.

[0016] As a further improvement of this utility model, when the driving member rotates to the third rotation position, the inlet is only connected to the second outlet, and the micro switch is not triggered.

[0017] When the drive unit rotates to the third rotation position, the inlet is connected only to the second outlet. The cold water entering the valve body from the inlet will flow out of the second outlet to the nozzle, bypassing the heater. Therefore, the microswitch does not need to be triggered. When the drive unit rotates to the third rotation position, the nozzle can spray cold water outward to meet the cleaning needs of the cleaning equipment.

[0018] As a further improvement of this utility model, the driving component is a knob, and the valve core assembly includes a spindle fixedly connected to the knob; The knob drives the valve core assembly to rotate via the spindle.

[0019] When using the cleaning equipment, users simply turn the knob, which drives the valve core assembly to the corresponding position via the spindle, making operation convenient.

[0020] As a further improvement of this utility model, the cleaning device is configured to control the rotation of the valve core assembly by rotating the driving component. The detection element is a potentiometer, which is connected to the driving component to output an electrical signal to the control circuit when the driving component is detected to move to a specific position.

[0021] A potentiometer can accurately detect the rotation angle of a driving component, thereby enabling the control circuit to accurately determine whether the driving component is in a specific position.

[0022] As a further improvement of this utility model, the cleaning device also includes an actuator for driving the valve core assembly to rotate. The driving element is electrically connected to the actuator to control the rotation of the valve core assembly through the actuator.

[0023] The drive unit indirectly drives the valve core assembly to rotate by controlling the actuator, which allows users to drive the valve core assembly to rotate more effortlessly, thus improving the user experience of the cleaning equipment.

[0024] As a further improvement of this utility model, the cleaning device is configured to control the rotation of the valve core assembly by rotating the driving component, and the detection element includes a magnetic component and a Hall element; The magnetic component is fixed to the driving component and moves with the driving component; or, the magnetic component is fixed to the valve core assembly and moves with the valve core assembly. The Hall element is used to output an electrical signal to the control circuit when it detects that the drive element or valve core assembly indicated by the magnetic element has moved to a specific position.

[0025] Hall effect sensors can accurately detect the position of a drive element or valve core assembly through magnetic components, allowing the control circuit to accurately determine whether the drive element or valve core assembly is in a specific position. Furthermore, during detection, the Hall effect sensor and the magnetic component do not need to be in contact, and both can be flexibly arranged.

[0026] Beneficial effects: In the cleaning equipment provided by this utility model, when the driving component or valve core assembly moves to a specific position that allows the inlet and the first outlet to connect, the detection element can output an electrical signal to the control circuit. After receiving the signal, the control circuit can control the heater to start, enabling the heater to heat the cold water entering it. The heater can start automatically when needed, without requiring manual control by the user. The control of the cleaning equipment is simple and convenient, improving the user experience.

[0029] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any modifications to the mechanism, method, or function made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0030] The terms used herein, such as "up," "down," "left," "right," "front," and "back," indicating spatial relative position, are for illustrative purposes to describe the relationship of one feature relative to another, as shown in the accompanying drawings. It is understood that, depending on the product's placement, these terms may be intended to include different orientations besides those shown in the figures, and should not be construed as limiting the claims. Furthermore, the descriptive term "horizontal" used herein is not entirely equivalent to being perpendicular to the direction of gravity, and allows for a certain angle of inclination.

[0031] like Figure 1-6 As shown, the first embodiment of this utility model provides a cleaning device 100, which can be used to clean dirt on the ground, walls and other surfaces.

[0032] The cleaning device 100 includes a nozzle 10 and a heater 20. The heater 20 is used to heat fluids; for example, the heater 20 can heat cold water entering it, turning the cold water into hot water or high-temperature steam. The outlet of the heater 20 is in fluid communication with the nozzle 10, and the hot water or steam generated by the heater 20 can flow to the nozzle 10, allowing the nozzle 10 to spray hot water or steam onto the roller brush of the cleaning device 100, thereby helping the roller brush to clean dirt on floors, walls, etc.

[0033] The cleaning device 100 also includes a valve assembly 30 and a drive unit 50. The valve assembly 30 includes a valve body 31 and a valve core assembly 32 disposed within the valve body 31. The valve body 31 has an inlet 311 and multiple outlets, allowing fluid to enter the valve body 31 through the inlet 311 and exit through the outlets. The multiple outlets include a first outlet 312, which is in fluid communication with the inlet of the heater 20. The drive unit 50 can control the rotation of the valve core assembly 32 via electric or mechanical actuation. The rotation of the valve core assembly 32 adjusts the communication between the inlet 311 and the multiple outlets.

[0034] The cleaning device 100 also includes a detection element 40. The detection element 40 outputs an electrical signal to the control circuit when it detects that the drive member 50 or the valve core assembly 32 has moved to a specific position. This specific position is defined as the position of the drive member 50 or the valve core assembly 32 when the inlet 311 is connected to the first outlet 312; that is, when the drive member 50 or the valve core assembly 32 moves to a position that connects the inlet 311 and the first outlet 312, the detection element 40 can output an electrical signal to the control circuit.

[0035] It is understandable that by driving the valve core assembly 32 to rotate, the connection between the inlet 311 and multiple outlets can be adjusted. Therefore, by detecting the position of the valve core assembly 32, it can be determined whether the inlet 311 and the first outlet 312 can be connected.

[0036] The valve core assembly 32 is driven by the drive member 50. Therefore, the movement of the drive member 50 and the movement of the valve core assembly 32 are in a corresponding relationship. By detecting the position of the drive member 50, the position of the valve core assembly 32 can be determined, and then it can be determined whether the inlet 311 and the first outlet 312 can be connected.

[0037] The heater 20 is electrically connected to the control circuit. The control circuit can control the heater 20 to start based on the electrical signal output by the detection element 40, so that the heater 20 can heat the fluid entering it. The control circuit may include at least one of a microprocessor, a programmable logic device, or a logic circuit built from discrete electronic components. For example, in one embodiment, the control circuit includes a microprocessor programmed to execute the aforementioned control logic. In another embodiment, the control circuit includes a relay and a logic gate circuit for maintaining the state of the relay. Thus, the start and stop of the heater 20 can be automatically linked to the operating state of the valve device 30, without requiring separate user operation.

[0038] In the cleaning equipment 100, when the inlet 311 is connected to the first outlet 312, the cold water input into the valve device 30 through the inlet 311 will flow out of the valve device 30 from the first outlet 312 to the heater 20. When the control circuit controls the heater 20 to start, the heater 20 will heat the cold water flowing into it, heating the cold water into hot water or high-temperature steam. After that, the hot water or high-temperature steam can flow to the nozzle 10.

[0039] In this embodiment, the cleaning device 100 may further include a storage tank 60 for storing cold water. The storage tank 60 is in fluid communication with the inlet 311 of the valve device 30, and the cold water in the storage tank 60 can flow into the valve body 31 through the inlet 311. A water pump 80 may be provided in the flow path between the storage tank 60 and the inlet 311. When the water pump 80 is working, it can pump the cold water 80 in the storage tank 60 into the valve body 31.

[0040] With the above configuration, when the drive element 50 or the valve core assembly 32 moves to a specific position that allows the inlet 311 and the first outlet 312 to connect, the detection element 40 can output an electrical signal to the control circuit. Upon receiving the signal, the control circuit can control the heater 20 to start, enabling the heater 20 to heat the cold water entering it. The heater 20 can start automatically when needed, without requiring manual control by the user. The control of the cleaning equipment 100 is simple and convenient, improving the user experience.

[0041] In this embodiment, the cleaning device 100 is configured to control the rotation of the valve core assembly 32 by means of a rotary drive 50. That is, by rotating the drive 50, the valve core assembly 32 can be driven to rotate, thereby adjusting the connection between the inlet 311 and multiple outlets.

[0042] The detection element 40 is a micro switch 41, which has a sensing end. When the sensing end is touched, the micro switch 41 is triggered and outputs an electrical signal to the control circuit. The micro switch 41 is located near the driving member 50. The sensing end of the micro switch 41 is fixedly disposed on the rotation path of the driving member 50, and the sensing end of the micro switch 41 faces the circumferential surface of the driving member 50. The driving member 50 is provided with a trigger part, which is disposed on the circumferential surface of the driving member 50. In this embodiment, the micro switch 41 and the driving part are designed as follows: when the driving member 50 rotates to a specific position, the trigger part on the driving member 50 will interfere with the sensing end of the micro switch 41, thereby triggering the micro switch 41 to output an electrical signal.

[0043] With the above configuration, when the drive unit 50 rotates to a specific position, the micro switch 41 can be accurately triggered to output an electrical signal. The control circuit can accurately determine whether the drive unit 50 is in a specific position through the micro switch 41, thereby deciding whether to control the heater 20 to start.

[0044] In this embodiment, two microswitches 41 are provided, namely a first microswitch 411 and a second microswitch 412. Specific positions include a first rotational position and a second rotational position, and the driving member 50 can rotate to the first rotational position and the second rotational position.

[0045] Specifically, when the drive unit 50 rotates to the first rotation position, the trigger part of the drive unit 50 interferes with the sensing end of the first micro switch 411, thereby triggering the first micro switch 411 to output an electrical signal to the control circuit.

[0046] When the drive unit 50 rotates to the second rotation position, the trigger part of the drive unit 50 will interfere with the sensing end of the first micro switch 411 and the sensing end of the second micro switch 412, thereby triggering the first micro switch 411 and the second micro switch 412 to output electrical signals to the control circuit.

[0047] It can be seen that when the driving component 50 rotates to the first rotation position, only the first micro switch 411 outputs an electrical signal to the control circuit. When the driving component 50 rotates to the second rotation position, both the first micro switch 411 and the second micro switch 412 output electrical signals to the control circuit. The control circuit can accurately determine whether the driving component 50 is in the first or second rotation position based on the received electrical signals.

[0048] In this embodiment, as Figure 4 As shown, when the drive component 50 rotates to the first rotation position, the inlet 311 connects to the first outlet 312, and the maximum flow rate between the two is the first flow rate. Figure 5 As shown, when the drive unit 50 rotates to the second rotation position, the inlet 311 also connects to the first outlet 312, and the maximum flow rate between the two is the second flow rate. The first flow rate is greater than the second flow rate.

[0049] With the above configuration, when the drive unit 50 rotates to the first rotation position, the maximum flow rate between the inlet 311 and the first outlet 312 is relatively large. At this time, a significant amount of cold water can be sequentially transported into the heater 20 through the inlet 311 and the first outlet 312. When the drive unit 50 rotates to the second rotation position, the maximum flow rate between the inlet 311 and the first outlet 312 is relatively small. At this time, a smaller amount of cold water can be sequentially output into the heater 20 through the inlet 311 and the first outlet 312.

[0050] When the power of heater 20 remains stable, it will heat the cold water into hot water when there is a lot of cold water inside, and it will easily heat the cold water into high-temperature steam when there is a little cold water inside. In this embodiment, when the drive unit 50 is in the first rotation position and the second rotation position, controlling the maximum flow rate between the inlet 311 and the first outlet 312 allows the heater 20 to produce hot water and steam respectively. Both hot water and steam can flow to the nozzle 10 and be sprayed from the nozzle 10 onto the roller brush, thereby meeting the working needs of the cleaning equipment 100.

[0051] It is understandable that the first flow rate, the second flow rate, and the power of the heater 20 are matched during the design phase to achieve the function of heating into hot water or steam.

[0052] In this text, the maximum flow rate between inlet 311 and first outlet 312 should be understood as the flow rate of fluid that can flow from inlet 311 to first outlet 312 per unit time at a specific flow rate. The maximum flow rate between inlet 311 and second outlet 313 should be understood as the flow rate of fluid that can flow from inlet 311 to second outlet 313 per unit time at a specific flow rate.

[0053] Furthermore, when the drive member 50 rotates to the first rotation position, the fluid output temperature of the heater 20 is the first temperature; when the drive member 50 rotates to the second rotation position, the fluid output temperature of the heater 20 is the second temperature. The first temperature is lower than the second temperature.

[0054] In the above configuration, when the drive unit 50 rotates to the first rotation position, the fluid output temperature of the heater 20 is low. At this time, the heater 20 will heat the cold water entering it into hot water. When the drive unit 50 rotates to the second rotation position, the fluid output temperature of the heater 20 is high. The heater 20 will quickly heat the cold water entering it into high-temperature steam.

[0055] Regarding the fluid output temperature, it should be noted that the heater 20 is permitted to heat the fluid within it to a maximum of the fluid output temperature. In this embodiment, the cleaning device 100 also includes a temperature sensor 70, which is used to sense the temperature of the fluid within the heater 20. The temperature sensor 70 is electrically connected to the control circuit, which can obtain the temperature of the fluid within the heater 20 through the temperature sensor 70. When the temperature sensor 70 detects that the temperature of the fluid within the heater 20 is greater than the set fluid output temperature, the control circuit can control the heater 20 to stop working or reduce its power to prevent the temperature of the fluid within the heater 20 from rising.

[0056] like Figure 3-6As shown, in this embodiment, the valve core assembly 32 is provided with a communication port 321, a first control port 322, and a second control port 323. An intermediate cavity 314 is formed inside the valve body 31. Furthermore, the valve body 31 is also formed with a first flow channel port 3111, a second flow channel port 3121, and a third flow channel port 3131 that cooperate with the valve core assembly 32. The inlet 311 is connected to the first flow channel port 3111, the first outlet 312 is connected to the second flow channel port 3121, and the second outlet 313 is connected to the third flow channel port 3131.

[0057] The rotation of the drive component 50 can drive the valve core assembly 32 to rotate. For example... Figure 4 As shown, when the driving member 50 rotates to the first rotation position, the first flow channel port 3111 connects to the intermediate cavity 314 through the connecting port 321, and the second flow channel port 3121 connects to the intermediate cavity 314 through the first control port 322. The inlet 311 can sequentially connect to the first outlet 312 through the first flow channel port 3111, the connecting port 321, the intermediate cavity 314, the first control port 322, and the second flow channel port 3121. When the driving member 50 rotates to the first rotation position, the overlapping area between the first control port 322 and the second flow channel port 3121 is the first area.

[0058] like Figure 5 As shown, when the driving member 50 rotates to the second rotation position, the first flow channel port 3111 connects to the intermediate cavity 314 through the connecting port 321, and the second flow channel port 3121 connects to the intermediate cavity 314 through the second control port 323. The inlet 311 can sequentially connect to the first outlet 312 through the first flow channel port 3111, the connecting port 321, the intermediate cavity 314, the second control port 323, and the second flow channel port 3121. When the driving member 50 rotates to the second rotation position, the overlapping area between the second control port 323 and the second flow channel port 3121 is the second area.

[0059] The first area defines the magnitude of the first flow rate, which is proportional to the size of the first area. Similarly, the second area defines the magnitude of the second flow rate, which is proportional to the size of the second area. In this embodiment, the first area is larger than the second area, thus making the first flow rate greater than the second flow rate.

[0060] The drive unit 50 can also rotate relative to the valve body 31 to a third rotational position. For example... Figure 6 As shown, when the drive unit 50 rotates to the third rotation position, the inlet 311 connects to the second outlet 313. After cold water enters the valve body 31 from the inlet 311, it flows out from the second outlet 313 to the nozzle 10. The nozzle 10 can spray cold water outward to meet the cleaning needs of the cleaning equipment 100.

[0061] In this embodiment, when the drive member 50 rotates to the third rotation position, the maximum flow rate between the inlet 311 and the second outlet 313 is the third flow rate, which is greater than the second flow rate. Thus, when the drive member 50 rotates to the third rotation position, a greater amount of cold water can flow to the nozzle 10.

[0062] When the drive unit 50 rotates to the third rotation position, the first flow channel 3111 connects to the intermediate cavity 314 through the connecting port 321, and the third flow channel 3131 connects to the intermediate cavity 314 through the first control port 322. The inlet 311 can connect to the second outlet 313 in sequence through the first flow channel 3111, the connecting port 321, the intermediate cavity 314, the first control port 322, and the third flow channel 3131.

[0063] When the drive member 50 rotates to the first rotation position, the second flow channel 3121 connects to the intermediate cavity 314 through the first control port 322. When the drive member 50 rotates to the third rotation position, the third flow channel 3131 connects to the intermediate cavity 314 through the first control port 322. The first control port 322 can be reused, which simplifies the structure of the valve device 30.

[0064] When the drive unit 50 rotates to the third rotation position, the overlapping area between the first control port 322 and the third flow channel port 3131 is the third area. The third area is larger than the second area, thus the third flow rate is greater than the second flow rate. The first area and the third area can be equal.

[0065] In this embodiment, the connecting port 321 is arc-shaped and extends along the circumferential direction of the valve core assembly 32. Thus, when the valve core assembly 32 rotates between the first rotation position, the second rotation position, and the third rotation position, the first flow channel port 3111 remains in communication with the intermediate cavity 314 through the connecting port 321. With the above configuration, the structure of the valve core assembly 32 is relatively simple.

[0066] The drive component 50 is a knob, and the valve core assembly 32 also includes a spindle 326, which is fixedly connected to the knob. The knob can drive the valve core assembly 32 to rotate via the spindle 326. When using the cleaning equipment 100, the user simply turns the knob, which drives the valve core assembly 32 to rotate to the corresponding position via the spindle 326, making operation convenient.

[0067] In other embodiments of this utility model, the cleaning device 100 may also be configured as follows: the actuator drives the valve core assembly 32 to rotate, thereby adjusting the communication relationship between the inlet 311 and multiple outlets. The drive member 50 is electrically connected to the actuator and can control the actuator to control the rotation of the valve core assembly 32.

[0068] The drive unit 50 indirectly drives the valve core assembly 32 to rotate by controlling the actuator, which allows the user to drive the valve core assembly 32 to rotate more effortlessly, improving the user experience of the cleaning equipment 100. For example, the drive unit 50 can be a button, and the actuator can be a motor. By pressing the button, the user can control the motor to move, thereby driving the valve core assembly 32 to rotate.

[0069] like Figure 7-12 As shown, the second embodiment of the present invention provides a cleaning device 100. In the cleaning device 100, the valve device 30 has multiple outlets including a first outlet 312 and a second outlet 313. The first outlet 312 is in fluid communication with the inlet of the heater 20, and the second outlet 313 is in fluid communication with the nozzle 10.

[0070] The cleaning device 100 also includes a mixing chamber 11. The inlet of the mixing chamber 11 is connected to the outlet of the heater 20 and the second outlet 313, respectively, and the outlet of the mixing chamber 11 is connected to the nozzle 10. The fluid flowing out of the outlet of the heater 20 and the fluid flowing out of the second outlet 313 can enter the mixing chamber 11 for mixing and then flow to the nozzle 10 after mixing.

[0071] In this embodiment, the specific position includes a first rotational position and a second rotational position, and the driving member 50 can rotate to the first rotational position and the second rotational position.

[0072] like Figure 10 As shown, when the drive unit 50 rotates to the first rotation position, the inlet 311 is simultaneously connected to the first outlet 312 and the second outlet 313, and the trigger part interferes with the sensing end of the micro switch 41.

[0073] like Figure 11 As shown, when the drive unit 50 rotates to the second rotation position, the inlet 311 is only connected to the first outlet 312, and the trigger part interferes with the sensing end of the micro switch 41.

[0074] With the above configuration, when the drive unit 50 rotates to the first rotation position, the cold water entering the valve body 31 from the inlet 311 can flow out in two separate streams from the first outlet 312 and the second outlet 313. One stream of cold water flows through the first outlet 312 to the heater 20, and after being heated into hot water by the heater 20, it flows into the mixing chamber 11. The other stream of cold water flows directly into the mixing chamber 11 through the second outlet 313. After the cold and hot water are mixed in the mixing chamber 11, they can flow to the nozzle 10, and the nozzle 10 can spray out warm water.

[0075] When the drive unit 50 rotates to the second rotation position, the inlet 311 is connected only to the first outlet 312. The cold water entering the valve body 31 from the inlet 311 will only flow to the heater 20 through the first outlet 312. The heater 20 can heat the cold water into high-temperature water vapor, and the water vapor will then flow to the nozzle 10. The nozzle 10 can spray out high-temperature water vapor.

[0076] In the cleaning device 100 provided in this embodiment, when the valve core assembly 32 is rotated to the first rotation position and the second rotation position, the micro switch 41 is triggered to send a signal to the control circuit. By controlling the valve core assembly 32 to rotate to the first rotation position and the second rotation position, the nozzle 10 can spray warm water and high-temperature water vapor respectively, thereby meeting the cleaning needs of the cleaning device 100.

[0077] like Figure 9-12 As shown, in this embodiment, the valve core assembly 32 is provided with a communication port 321, a first control port 322, a second control port 323, and a third control port 324. An intermediate cavity 314 is formed inside the valve body 31. Furthermore, the valve body 31 is also formed with a first flow channel port 3111, a second flow channel port 3121, and a third flow channel port 3131 that cooperate with the valve core assembly 32. The inlet 311 is connected to the first flow channel port 3111, the first outlet 312 is connected to the second flow channel port 3121, and the second outlet 313 is connected to the third flow channel port 3131.

[0078] The rotation of the drive component 50 can drive the valve core assembly 32 to rotate. For example... Figure 10 As shown, when the drive unit 50 rotates to the first rotation position, the first flow channel 3111 connects to the intermediate cavity 314 through the connecting port 321, the second flow channel 3121 connects to the intermediate cavity 314 through the first control port 322, and the third flow channel 3131 connects to the intermediate cavity 314 through the second control port 323.

[0079] With the above configuration, when the drive unit 50 rotates to the first rotation position, the inlet 311 can sequentially connect to the first outlet 312 through the first flow channel 3111, the connecting port 321, the intermediate cavity 314, the first control port 322, and the second flow channel 3121. The inlet 311 can also sequentially connect to the second outlet 313 through the first flow channel 3111, the connecting port 321, the intermediate cavity 314, the second control port 323, and the third flow channel 3131. Thus, the inlet 311 can simultaneously connect to the first outlet 312 and the second outlet 313.

[0080] When the drive unit 50 rotates to the first position, the overlapping area of ​​the second flow channel 3121 and the first control port 322 is the fourth area, and the overlapping area of ​​the third flow channel 3131 and the second control port 323 is the fifth area. It can be imagined that by adjusting the ratio of the fourth area and the fourth and fifth areas, the ratio of hot and cold water entering the mixing chamber 11 can be controlled, thereby controlling the temperature of the warm water mixed in the mixing chamber 11.

[0081] like Figure 11 As shown, when the drive member 50 rotates to the second rotation position, the first flow channel port 3111 connects to the intermediate cavity 314 through the connecting port 321, and the second flow channel port 3121 connects to the intermediate cavity 314 through the third control port 324. The inlet 311 can sequentially connect to the first outlet 312 through the first flow channel port 3111, the connecting port 321, the intermediate cavity 314, the third control port 324, and the second flow channel port 3121. Thus, when the drive member 50 rotates to the second rotation position, the inlet 311 only connects to the first outlet 312.

[0082] The drive unit 50 also has a third rotational position, such as Figure 12 As shown, when the drive unit 50 rotates to the third rotation position, the inlet 311 is only connected to the second outlet 313, and the micro switch 41 is not triggered.

[0083] When the drive unit 50 rotates to the third rotation position, the inlet 311 is only connected to the second outlet 313. The cold water entering the valve body 31 from the inlet 311 will flow out of the second outlet 313 to the nozzle 10 without passing through the heater 20. Therefore, the micro switch 41 does not need to be triggered. When the drive unit 50 rotates to the third rotation position, the nozzle 10 can spray cold water outward to meet the cleaning needs of the cleaning equipment 100.

[0084] The valve core assembly 32 is also provided with a fourth control port 325. When the drive member 50 rotates to the third rotation position, the first flow channel port 3111 connects to the intermediate cavity 314 through the connecting port 321, and the third flow channel port 3131 connects to the intermediate cavity 314 through the fourth control port 325. The inlet 311 can connect to the second outlet 313 in sequence through the first flow channel port 3111, the connecting port 321, the intermediate cavity 314, the fourth control port 325, and the third flow channel port 3131.

[0085] When the drive member 50 rotates to the second rotation position, the maximum flow rate between the second flow channel port 3121 and the third control port 324 is the fourth flow rate. When the drive member 50 rotates to the third rotation position, the maximum flow rate between the third flow channel port 3131 and the fourth control port 325 is the fifth flow rate. In this embodiment, the fourth flow rate is less than the fifth flow rate.

[0086] With the above configuration, when the drive unit 50 rotates to the second rotation position, less cold water can flow into the heater 20, and the heater 20 can easily heat the cold water into water vapor. When the drive unit 50 rotates to the third rotation position, more cold water can flow to the nozzle 10, so that the nozzle 10 can spray out a large amount of cold water for the cleaning equipment 100 to clean dirt.

[0087] When the drive unit 50 rotates to the second rotation position, the overlapping area between the second flow channel port 3121 and the third control port 324 is the sixth area. When the drive unit 50 rotates to the third rotation position, the overlapping area between the third flow channel port 3131 and the fourth control port 325 is the seventh area. The sixth area is smaller than the seventh area, thus making the fourth flow rate smaller than the fifth flow rate.

[0088] Other features of this embodiment can be found in the first embodiment described above.

[0089] In the third embodiment of this utility model, the cleaning device 100 is configured to control the rotation of the valve core assembly 32 by means of a rotary drive 50. That is, by rotating the drive 50, the valve core assembly 32 can be driven to rotate, thereby adjusting the connection relationship between the inlet 311 and multiple outlets.

[0090] In this embodiment, the detection element 40 is a potentiometer. The potentiometer is connected to the driving element 50 and can detect the rotation angle of the driving element 50. When the driving element 50 rotates to a specific position, the potentiometer can send a signal to the control circuit. After receiving the signal, the control circuit can control the heater 20 to start.

[0091] In this embodiment, the potentiometer can accurately detect the rotation angle of the driving component 50, so that the control circuit can accurately determine whether the driving component 50 is in a specific position.

[0092] Other features of this embodiment can be found in the first embodiment described above.

[0093] In the fourth embodiment of this utility model, the cleaning device 100 is configured to control the rotation of the valve core assembly 32 by means of a rotary drive 50. That is, by rotating the drive 50, the valve core assembly 32 can be driven to rotate, thereby adjusting the connection relationship between the inlet 311 and multiple outlets.

[0094] In this embodiment, the detection element 40 includes a magnetic component and a Hall element. The magnetic component is fixed to the driving component 50 and can rotate with the driving component 50. The Hall element can detect the position of the magnetic component. When the Hall element detects that the driving component 50, indicated by the magnetic component, has moved to a specific position, it can output an electrical signal to the control circuit. After receiving the signal, the control circuit can control the heater 20 to start.

[0095] In this embodiment, the Hall element can accurately detect the position of the driving element 50 through the magnetic component, thereby enabling the control circuit to accurately determine whether the driving element 50 is in a specific position. Furthermore, during detection, the Hall element and the magnetic component do not need to be in contact, and both can be flexibly arranged.

[0096] Other features of this embodiment can be found in the first embodiment described above.

[0097] In the fifth embodiment of this utility model, the following configuration can also be made: the magnetic element is fixed to the valve core assembly 32 and can rotate with the valve core assembly 32. When the Hall element detects that the valve core assembly 32, indicated by the magnetic element, has moved to a specific position, it can output an electrical signal to the control circuit. After receiving the signal, the control circuit can control the heater 20 to start.

[0098] In this embodiment, the Hall element can accurately detect the position of the valve core assembly 32 through the magnetic component, thereby enabling the control circuit to accurately determine whether the valve core assembly 32 is in a specific position. Furthermore, during detection, the Hall element and the magnetic component do not need to be in contact, and both can be flexibly arranged.
