[0002] Existing thermostatic valves rely solely on the tightening force of the compressed sealing ring for limiting the water temperature during installation. However, if the user applies excessive torque when adjusting the water temperature (by rotating the end of the thermostatic valve), the entire thermostatic valve will rotate, leading to inaccurate water temperature adjustment. Utility Model Content

[0003] The main purpose of this invention is to provide a knob adjustment device and a cleaning machine, which aims to avoid the situation where excessive rotational force on the mixing valve causes the thermostatic valve to rotate as a whole, resulting in inaccurate water temperature adjustment.

[0016] In one embodiment, the adjusting member is slidably disposed on the knob body along the radial direction of the knob body, and the rotary adjusting assembly further includes an elastic member that elastically connects the adjusting member and the knob body, the elastic member being used to provide a restoring force that causes the adjusting member to slide out toward a side away from the center of the knob body.

[0017] In one embodiment, the knob body has a first guide groove extending radially along the knob body, and the adjusting member is slidably disposed in the first guide groove; and / or

[0021] This utility model also proposes a cleaning machine, comprising:

[0022] Water storage containers; and

[0023] As described above, the mixing valve and valve fixing component of the knob adjustment device are fixed to the water storage container.

[0024] In one embodiment, the water storage container includes a container body and a mounting part. The mounting part protrudes from the container body and has a through mounting channel. The mixing valve is inserted into the mounting channel, and the valve fixing member is detachably mounted on the mounting part.

[0025] In one embodiment, the valve body of the mixing valve has a raised edge on its outer periphery, and the inner wall of the mounting channel has a stepped surface, which abuts against the raised edge.

[0026] And / or, the mounting part is provided with a positioning hole on its periphery, and the valve fixing member is provided with a positioning part on the side facing the mounting part, and the positioning part is provided with a positioning protrusion that positions and cooperates with the positioning hole.

[0027] In one embodiment, a limiting groove is provided along the edge of the installation channel, and a positioning rib is provided on the side of the valve fixing member facing the installation part to engage with the limiting groove.

[0028] In one embodiment, the limiting groove includes a first limiting groove and a second limiting groove, the width of the first limiting groove being greater than the width of the second limiting groove, and the positioning rib includes a first positioning rib and a second positioning rib, the first positioning rib being inserted into the first limiting groove and the second positioning rib being inserted into the second limiting groove.

[0029] In one embodiment, the container body has a first water cavity and a second water cavity, the first water cavity being connected to an external hot water source, the second water cavity being connected to an external ambient temperature water source, and the mixing valve of the knob adjustment device being connected to the first water cavity and the second water cavity respectively.

[0030] The technical solution of this utility model is to set a valve fixing component, which can be connected and fixed to the water storage container. The valve fixing component has a first limiting structure. When the mixing valve is installed on the water storage container through the valve body of the mixing valve, the first limiting structure can form a cooperation relationship with the valve body, restricting the rotation of the valve body in the circumferential direction. When the valve core is rotated by turning the rotary adjustment component to adjust the water temperature, the valve body is restricted from rotating in the circumferential direction by the first limiting structure. Therefore, even if the valve core rotates excessively and forms a circumferential rotational force on the valve body, it will not drive the valve body to rotate, causing the mixing valve to rotate in the circumferential direction as a whole. When this knob adjustment device is applied to the water outlet device, it avoids the situation where the thermostatic valve rotates as a whole due to excessive rotational force on the mixing valve, resulting in inaccurate water temperature adjustment.

[0049] Existing thermostatic valves rely solely on the tightening force of the compressed sealing ring for temperature control during installation. However, when adjusting the water temperature (by rotating the valve end), excessive torque can cause the entire valve to rotate, leading to inaccurate temperature adjustment. Furthermore, during routine temperature adjustments, especially when adjusting the heating element, the existing knob lacks a limit switch, making it easy to operate and potentially causing burns if accidentally operated by a child or adult.

[0050] This utility model proposes a knob adjustment device to solve the problem that excessive torque during the rotation adjustment of a thermostatic valve causes the thermostatic valve to deflect as a whole, resulting in inaccurate water temperature adjustment. It also proposes to set the stroke of the thermostatic valve rotation adjustment to prevent accidental operation and the problem that the water outlet temperature of the water outlet device is too high, which may cause scalding.

[0051] Please see Figures 1 to 10 In one embodiment of this utility model, the knob adjustment device includes a mixing valve 20, a rotary adjustment assembly 30, and a valve fixing member 40. The mixing valve 20 includes a valve body 21 and a valve core 22. The valve body 21 is installed on the water storage container 10, and the valve core 22 is rotatably disposed on the valve body 21. The rotary adjustment assembly 30 is drivenly connected to the valve core 22. The rotary adjustment assembly 30 is used to rotate under the action of an external force to drive the valve core 22 to rotate. The valve fixing member 40 is used to connect and fix to the water storage container 10. The valve fixing member 40 has a first limiting structure that cooperates with the valve body 21. The first limiting structure is used to restrict the valve body 21 from circumferentially rotating.

[0052] In this invention, a knob adjustment device can be applied to a cleaning machine 100 to adjust the water output of the cleaning machine 100. The cleaning machine 100 may include a water storage container 10, and the knob adjustment device is disposed in the water storage container 10. The mixing valve 20 and valve fixing member 40 of the knob adjustment device are fixed to the water storage container 10.

[0053] The water storage container 10 can be configured as a water tank, which may contain a first water chamber and a second water chamber. A mixing valve 20 is connected to both the first and second water chambers. The first water chamber can be connected to an external hot water source to store hot water supplied by the municipal water supply system. The hot water can be between 40 and 80 degrees Celsius, although the specific temperature range may vary depending on the region. The second water chamber can be connected to an external ambient temperature water source to store ambient temperature water supplied by the municipal water supply system. Ambient temperature water is the tap water supplied by the municipal system, typically between 10 and 25 degrees Celsius. The specific temperature is affected by season and environment; in winter, the ambient temperature is usually lower, and in summer, it is usually higher.

[0054] In this invention, rotating the valve core 22 within the valve body 21 allows for adjustment of the outlet water temperature of the mixing valve 20. For example, rotating the valve core 22 clockwise increases the outlet water temperature of the mixing valve 20, while rotating it counterclockwise decreases the outlet water temperature. Alternatively, rotating the valve core 22 clockwise decreases the outlet water temperature of the mixing valve 20, and rotating it counterclockwise increases the outlet water temperature of the mixing valve 20. The direction of rotation is not specifically limited.

[0055] When the knob adjustment device is applied to a water storage device, an installation channel 111 can be provided on the water storage container 10 for inserting and installing the mixing valve 20 of the knob adjustment device. The valve fixing part 40 of the knob adjustment device can be fixed to the outer surface of the water storage container 10 by means of snap-fit, riveting, plugging, etc. When the valve fixing part 40 is fixed to the water storage container 10, the first limiting structure on the valve fixing part 40 can form a limiting engagement relationship with the valve body 21. When the valve core 22 of the mixing valve 20 rotates in the valve body 21 to adjust the outlet water temperature, the first limiting structure can restrict the circumferential rotation of the valve body 21. Even if the rotation angle of the valve core 22 is too large, when a circumferential rotational force is applied to the valve body 21, it will not cause the valve body 21 to rotate circumferentially, thus preventing the valve body 21 from shifting.

[0056] The technical solution of this utility model is to set a valve fixing component 40 so that the valve fixing component 40 can be connected and fixed to the water storage container 10, and the valve fixing component 40 has a first limiting structure. When the mixing valve 20 is installed on the water storage container 10 through the valve body 21 of the mixing valve 20, the first limiting structure can form a cooperation relationship with the valve body 21 to restrict the rotation of the valve body 21 in the circumferential direction. When the valve core 22 is rotated by turning the rotary adjustment component 30 to adjust the water temperature, the valve body 21 is restricted from rotating in the circumferential direction by the first limiting structure. Therefore, even if the valve core 22 rotates excessively and forms a circumferential rotational force on the valve body 21, it will not drive the valve body 21 to rotate, causing the mixing valve 20 to rotate in the circumferential direction as a whole. When this knob adjustment device is applied to the water outlet device, it avoids the situation where the thermostatic valve rotates as a whole due to excessive rotational force on the mixing valve 20, resulting in inaccurate water temperature adjustment.

[0057] See Figure 4 , Figure 6 As shown, in one embodiment, the valve fixing member 40 includes a fixing ring 41 sleeved on the outer periphery of the valve body 21. The first limiting structure is provided on the side of the fixing ring 41 facing the valve body 21. The first limiting structure is a limiting plane 411 provided on the inner peripheral wall of the fixing ring 41. The outer peripheral wall of the valve body 21 is provided with a mating plane 211 opposite to the limiting plane 411. The limiting plane 411 abuts against the mating plane 211 to restrict the valve body 21 from circumferentially rotating.

[0058] In the above embodiment, since the limiting plane 411 of the fixed ring 41 and the mating plane 211 on the outer periphery of the valve body 21 can abut and fit, the circumferential rotation of the valve body 21 relative to the fixed ring 41 can be restricted. When the valve fixing member 40 is connected and fixed to the water storage container 10, the valve fixing member 40 and the water storage container 10 form a mating and fixed relationship, thereby restricting the circumferential rotation of the valve body 21 relative to the water storage container 10. When the mixing valve 20 is installed and fixed for use, excessive twisting of the valve core 22 can be avoided, which would cause the mixing valve 20 to deflect as a whole. The limiting plane 411 provided on the inner peripheral wall of the fixed ring 41 can be one, two, or three, and the specific number is not limited.

[0059] In this utility model, in order to further prevent the valve core 22 from rotating excessively and to control the rotation stroke of the valve core 22, and to prevent the water outlet of the mixing valve 20 from being too hot and causing scalding, or the water outlet from being too cold and causing discomfort, optionally, the valve fixing member 40 also has a second limiting structure that cooperates with the rotation adjustment component 30. The second limiting structure is located on the side of the fixing ring 41 opposite to the first limiting structure, and the second limiting structure is used to limit the rotation stroke of the rotation adjustment component 30.

[0060] In the above embodiment, since the rotary adjustment component 30 is connected to the valve core 22 of the mixing valve 20, when the rotary adjustment component 30 is turned by hand, it will drive the valve core 22 to rotate and adjust the outlet water temperature of the mixing valve 20. By setting a second limiting structure on the valve fixing component 40, the rotation stroke of the rotary adjustment component 30 is limited, so that the rotary adjustment component 30 has a controllable rotation stroke. Thus, the beginning and end of the rotation stroke can be set accordingly. For example, the beginning of the rotation stroke can be set to the lowest point of the outlet water temperature of the mixing valve 20, and the end of the rotation stroke can be set to the highest point of the outlet water temperature of the mixing valve 20. This can avoid the valve core 22 from rotating too much and causing an unsuitable outlet water temperature, and at the same time, it can also avoid the valve core 22 from rotating too much and causing the valve body 21 to deflect. Furthermore, since the second limiting structure needs to cooperate with the rotary adjustment component 30 to limit the rotation of the rotary adjustment component 30, the second limiting structure can be set on the side of the valve fixing member 40 facing the rotary adjustment component 30. The first limiting structure needs to cooperate with the valve body 21 to limit the circumferential rotation of the valve body 21, so the first limiting structure can be set on the side of the valve fixing member 40 close to the valve body 21.

[0061] See Figure 2 , Figure 6 , Figure 7 As shown, in one embodiment, the fixing ring 41 includes a first ring portion 41a extending toward the valve body 21. The first ring portion 41a has two opposing arcuate segments and two opposing straight segments. The inner walls of the two straight segments respectively form two limiting planes 411. The outer peripheral wall of the valve body 21 is provided with two opposing mating planes 211. This arrangement allows the first limiting structure to abut against the mating planes 211 on the valve body 21 through the two opposing limiting planes 411, thereby effectively limiting the circumferential deflection of the valve body 21.

[0062] In addition, the fixing ring 41 also includes a second ring body portion 41b, which is disposed on the side of the first ring body portion 41a away from the valve body 21, and the second limiting structure is disposed on the side of the second ring body portion 41b away from the first ring body portion 41a.

[0063] See Figure 7 , Figure 8As shown, in one embodiment, the valve fixing member includes a fixing ring 41 sleeved on the outer periphery of the valve body 21. The second limiting structure includes a first limiting part 442 and a second limiting part 443. The first limiting part 442 and the second limiting part 443 are disposed on the side of the fixing ring 41 facing the rotary adjustment assembly 30. The rotary adjustment assembly 30 includes a knob body 31 and a movable rod 32. The knob body 31 is connected to the valve core 22 and is used to drive the valve core 22 to rotate under the action of external force. The movable rod 32 is connected to the knob body 31 and can rotate with the knob body 31. The first limiting part 442 and the second limiting part 443 are located on the rotation path of the movable rod 32. The movable rod 32 has a first position abutting against the first limiting part 442 and a second position abutting against the second limiting part 443.

[0064] With this configuration, when the knob body 31 is rotated, the movable rod 32 can be rotated synchronously. Since the first limiting part 442 and the second limiting part 443 are located on the rotation path of the movable rod 32, when the movable rod 32 is rotated synchronously, the movable rod 32 can abut against the first limiting part 442 and the second limiting part 443. Thus, it can be set that when the valve core 22 rotates to make the mixing valve 20 have the maximum limited outlet water temperature, the movable rod 32 abuts against the first limiting part 442, and when the valve core 22 rotates to make the mixing valve 20 have the minimum limited outlet water temperature, the movable rod 32 abuts against the second limiting part 443.

[0065] The fixed ring 41 may have a mounting surface on the side facing the rotation adjustment component 30. The mounting surface surrounds the outer periphery of the through hole in the middle of the fixed ring 41. The first limiting part 442 and the second limiting part 443 may be provided on the aforementioned mounting surface.

[0066] When the movable lever 32 rotates with the knob body 31, in order to ensure that the movable lever 32 moves along a set track, this utility model also provides a track component 44 to guide at least part of the rotational stroke of the movable lever 32. The track component 44 can be set on the aforementioned mounting surface, and the relevant settings are as follows. (Continue reading) Figure 7 , Figure 8 In one embodiment, the valve fixing member 40 further includes a track member 44 disposed on the side of the fixing ring 41 facing the rotation adjustment assembly 30. The track member 44 is provided with a track groove 441. The movable rod 32 is slidably engaged with the track groove 441. The track groove 441 has a slot for the movable rod 32 to enter and exit. The first limiting part 442 is disposed in the track groove, and the second limiting part 443 is disposed outside the track groove.

[0067] When the first limiting part 442 is located inside the track groove 441, the first limiting part 442 can be configured as the inner wall of the track member 44 facing the movable rod 32, or the first limiting part 442 can be a protruding structure provided in the track groove 441. When the second limiting part 443 is located outside the track groove 441, the second limiting part 443 can be provided on the periphery of the groove opening of the track groove 441, or the second limiting part 443 can be provided on the outer wall of the track member 44 and located on the rotation path of the movable rod 32. When the second limiting part 443 is provided on the inner wall of the track member 44 facing the movable rod 32, the second limiting part 443 can be provided opposite to the first limiting part 442. Alternatively, in other embodiments, the first limiting part 442 can be provided outside the track groove 441 and the second limiting part 443 can be provided inside the track groove 441, which is not limited here.

[0068] When the second limiting part 443 is disposed on the outer wall of the track member 44 and located on the rotation path of the movable rod 32, a third limiting part 444 can also be disposed between the first limiting part 441 and the second limiting part 443. To avoid interference when the movable rod 32 moves between the first position and the second position due to the placement of the third limiting part 444, when the movable rod 32 approaches the third limiting part 444, the third limiting part 444 is positioned so that it can approach the movable rod 32, causing the movable rod 32 to abut against the third limiting part 444. This allows the mixing valve 20 to set an intermediate outlet temperature between the highest and lowest outlet temperatures when discharging water. At the same time, when the movable rod 32 approaches the third limiting part 444, the third limiting part 444 can move relative to the movable rod 32, allowing the third limiting part 444 to move away from the movable rod, preventing the third limiting part 444 from abutting against the movable rod 32. This allows the default outlet water temperature of the mixing valve 20 to be set at the position where the movable rod 32 abuts against the third limit part 444, thus reducing the adjustment stroke of the mixing valve 20 when adjusting for hot or cold water.

[0069] In the above embodiments, regarding the ability of the third limiting part 444 to move closer to or further away from the movable rod 32, the third limiting part 444 may remain stationary at a preset position. While the movable rod 32 is rotating in a circular motion, it may also move radially, causing relative movement between the movable rod 32 and the third limiting part 444, thereby allowing the movable rod 32 to abut against the third limiting part 444. Alternatively, the movable rod 32 may only rotate in a circular motion without radial movement. When the movable rod 32 rotates to approach the third limiting part 444, the third limiting part 444 moves to abut against or move away from the movable rod 32. No specific limitations are imposed here.

[0070] Continue reading Figure 7 , Figure 8In one embodiment, the second limiting structure further includes a third limiting part 444, which is disposed outside the slot. The movable rod 32 also has a third position that abuts against the third limiting part 444. The rotary adjustment assembly 30 further includes an adjustment member 33 connected to the movable rod 32. The adjustment member 33 is movably disposed on the knob body 31. The adjustment member 33 is used to drive the movable rod 32 to move under the action of external force, so that the movable rod 32 can move from the third position into the track slot 441.

[0071] When the valve core 22 is rotated via the knob body 31, the adjusting member 33 located on the knob body 31 moves the movable rod 32. Since the third position is between the first and second positions, when the movable rod 32 is in the third position abutting against the third limiting part 444, the mixing valve 20 can have an intermediate outlet water temperature. Because the third limiting part 444 is located outside the track groove 441, when the movable rod 32 is in the third position abutting against the third limiting part 444, the adjusting member 33 needs to move the movable rod 32 to a certain position so that the movable rod 32 can move from the third position into the track groove 441. When the outlet water temperature of the mixing valve 20 needs to be increased, the adjusting member 33 needs to be operated to move the movable rod 32 so that the movable rod 32 is on the extension path of the track groove 441, allowing the movable rod 32 to rotate towards the track groove 441 and abut against the first limiting part 442 as the knob body 31 moves. This prevents children from accidentally operating the knob body 31 and increasing the water temperature.

[0072] The specific configuration of the first limiting part 442, the second limiting part 443, and the third limiting part 444 will be further described below. (Continue reading...) Figure 7 , Figure 8 Optionally, the track component 44 includes a first rib 44a, a second rib 44b, and a third rib 44c. The first rib 44a, the second rib 44b, and the third rib 44c surround and form the track groove 441. The first rib 44a and the second rib 44b are arranged radially at intervals along the fixing ring 41 and extend circumferentially along the fixing ring 41. The first limiting part 442 is provided on the side of the third rib 44c facing the groove opening, the second limiting part 443 is provided on the side of the third rib 44c away from the groove opening, and the third limiting part 444 is provided on the side of the first rib 44a away from the third rib 44c.

[0073] The first rib 44a, the second rib 44b, and the third rib 44c can be integrally formed on the side of the fixing ring 41 facing the knob body 31. The extension direction of the first rib 44a and the second rib 44b can be arc-shaped, and the extension direction of the first rib 44a and the second rib 44b can be located on the outer circle with the rotation center of the knob body 31 as the center. When the track groove 441 is formed by the first protrusion 44a, the second protrusion 44b, and the third protrusion 44c, the track groove 441 has only one opening. Thus, when the first limiting part 442 is positioned on the side of the third protrusion 44c facing the groove opening, and the second limiting part 443 is positioned on the side of the third protrusion 44c away from the groove opening, the movable rod 32 can abut against the first limiting part 442 when moving inside the track groove 441, and against the second limiting part 443 when moving outside the track groove 441. Furthermore, when the movable rod 32 moves outside the track groove 441, its position can be adjusted by the adjusting member 33 so that the movable rod 32 abuts against the end of the first protrusion 44a facing inside the track groove 441, rather than entering the track groove 441. This allows the movable rod 32 to have a first position, a second position, and a third position. Furthermore, the preset position of the movable rod 32 can be set to the second position, so that the mixing valve 20 has an intermediate outlet water temperature.

[0074] In other embodiments, the first protruding rib 44a, the second protruding rib 44b, and the third protruding rib 44c can be installed on the side of the fixing ring 41 facing the knob body 31 using an assembly-type connection. The first protruding rib 44a, the second protruding rib 44b, and the third protruding rib 44c can be assembled with the fixing ring 41 using snap-fit, threaded assembly, welding, or other methods. The first protruding rib 44a, the second protruding rib 44b, and the third protruding rib 44c can also be assembled with each other using snap-fit, threaded assembly, welding, or other methods. No specific limitations are made here.

[0075] To ensure that the movable lever 32 can be in the third movement position in its natural state, refer to... Figure 8 , Figure 10 As shown, optionally, the adjusting member 33 is slidably disposed on the knob body 31 along the radial direction of the knob body 31. The rotary adjusting assembly 30 further includes an elastic member 34, which elastically connects the adjusting member 33 and the knob body 31. The elastic member 34 is used to provide a restoring force that causes the adjusting member 33 to slide away from the center of the knob body 31.

[0076] The adjusting member 33 can be configured as a button or a push rod. It is understood that since the adjusting member 33 is slidably disposed radially on the knob body 31, and the adjusting member 33 is connected to the knob body 31 by an elastic member 34, and the elastic member 34 is used to allow the adjusting member 33 to slide out toward the side away from the center of the knob body 31 in its natural state, the movable rod 32 is in the default state on the side away from the center of the knob body 31, that is, it can abut against the third limiting part 444, so that the mixing valve 20 can be set to the intermediate outlet water temperature by default.

[0077] When the adjusting member 33 is slidably disposed radially on the knob body 31, a first guide groove 311 can be formed on the knob body 31 to guide the movement of the adjusting member 33. The adjusting member 33 is then placed in the first guide groove 311, allowing it to be precisely guided during movement. The relevant configuration is as follows. (See reference) Figure 8 As shown, in one embodiment, the knob body 31 has a first guide groove 311 extending radially along the knob body 31, and the adjusting member 33 is slidably disposed in the first guide groove 311. An elastic member 34 may be disposed within the first guide groove 311, with one end of the elastic member 34 connected to the groove wall and the other end connected to the adjusting member 33.

[0078] When the adjusting member 33 drives the movable rod 32 to move, in order to limit the movement stroke of the movable rod 32, a second guide groove 312 can be opened on the knob body 31, so that the movable rod 32 can be slidably installed in the second guide groove 312. The relevant settings are as follows. (Continue reading) Figure 8 Optionally, the knob body 31 has a second guide groove 312 extending radially along the knob body 31, and the movable rod 32 is slidably disposed in the second guide groove 312. This arrangement prevents the movable rod 32 from sliding into the slot facing the fixed ring 41 or sliding out of the outer surface of the fixed ring 41 during movement, thus preventing the movable rod 32 from abutting against the first limiting part 442, the second limiting part 443, and the third limiting part 444 during movement.

[0079] When the movable rod 32 is in the third position, and the movable rod 32 moves toward the extension path of the track groove 441 driven by the adjusting member 33, in order to further prevent the movable rod 32 from sliding into the slot facing the fixed ring 41, the present invention can also extend the end of the second rib 44b away from the third rib 44c by an appropriate length. When the movable rod 32 moves toward the center of the knob body 31, it can abut against the extended part of the second rib 44b. This can further prevent the movable rod 32 from sliding into the slot facing the fixed ring 41 and disengaging from the second guide groove 312, resulting in the movable rod 32 being unable to abut against the first limiting part 442. The relevant settings are as follows. Optionally, the second rib 44b is located on the side of the first rib 44a near the center of the fixing ring 41. The second rib 44b includes a first sub-rib segment 44b1 and a second sub-rib segment 44b2. The second sub-rib segment 44b2 is located at the end of the first sub-rib segment 44b1 away from the third rib 44c. The first sub-rib segment 44b1 is disposed opposite to the first rib 44a, and the second sub-rib segment 44b2 is a section extending beyond the first rib 44a near the groove opening. With this configuration, when the movable rod 32 is in the third position and moves toward the extension direction of the track groove 441, it can be limited by the second sub-rib segment 44b2, so that the movable rod 32 is in the extension direction of the track groove 441, thereby being able to slide into the track groove 441 and abut against the first limiting part 442.

[0080] The outlet water temperature of the mixing valve 20 is further described below. In one embodiment, when the movable rod 32 is in the first position, the mixing valve 20 has a first outlet water temperature; when the movable rod 32 is in the second position, the mixing valve 20 has a second outlet water temperature; and when the movable rod 32 is in the third position, the mixing valve 20 has a third outlet water temperature, wherein the first outlet water temperature, the third outlet water temperature, and the second outlet water temperature decrease sequentially.

[0081] In this invention, since the first limiting part 442, the third limiting part 444, and the second limiting part 443 are sequentially arranged along the rotation path of the knob body 31, when the knob body 31 is turned, causing the movable rod 32 to move from the first position abutting against the first limiting part 442 to the third position abutting against the second limiting part 443, the outlet water temperature of the mixing valve 20 can change from high to low or from low to high. Because the first limiting part 442 is located within the track groove 441, when the movable rod 32 moves from the third position towards the first position, it requires operation of the adjusting member 33. Therefore, when the movable rod 32 is in the first position and water is being discharged, further operation is required. Thus, the outlet water temperature of the mixing valve 20 when the movable rod 32 is in the first position can be set to be higher than the outlet water temperature when the movable rod 32 is in the third position, thereby further ensuring the safety of the high-temperature water discharge from the water storage container 10 to which the mixing valve 20 is applied.

[0082] This utility model also proposes a cleaning machine 100, which includes a water storage container 10 and the aforementioned knob adjustment device. The specific structure of the knob adjustment device is as described in the above embodiments. Since this cleaning machine 100 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, and will not be described in detail here. The mixing valve 20 and valve fixing member 40 of the knob adjustment device are fixed to the water storage container 10.

[0083] In this invention, the water storage container 10 can be configured as a water tank, which serves as a water storage device for the cleaning machine 100. It is understood that the cleaning machine 100 can be used as a household appliance or a commercial appliance. The cleaning machine 100 has various uses, such as serving as a shower machine for users to bathe; or as a cleaning device for furniture and household items, used to clean electrical appliances, furniture products, etc. The specific use is not limited. The water storage container includes a container body and a partition disposed within the container body. The partition divides the inner cavity of the container body into a first water chamber and a second water chamber. The mixing valve 20 is disposed near the lower end of the partition.

[0084] Regarding the arrangement of the partition within the container body, it can be arranged from top to bottom, with the upper end of the partition connected to the upper end of the inner cavity of the container body, and the lower end of the partition spaced apart from the lower end of the inner cavity of the container body. The mounting part 11 can be extended into the inner cavity of the container body and connected to the lower end of the partition and the lower end of the inner cavity of the container body. The mounting channel 111 of the mounting part 11 extends into the inner cavity of the container body. When the mixing valve 20 is inserted into the mounting channel 111, the mixing valve 20 is located between the lower end of the partition and the bottom wall of the inner cavity of the container body.

[0085] In another embodiment, the water storage container 10 can also be configured as a first water tank and a second water tank, which can be separate structures; or, the first water tank and the second water tank can be an integrated structure. When the first water tank and the second water tank are separate structures, it is convenient to manufacture and install them separately, and it is also convenient to maintain or clean either one. When the first water tank and the second water tank are an integrated structure, the water storage container has a compact structure, the integrated design reduces material usage and installation costs, and the structure is more robust.

[0086] The cleaning machine 100 of this utility model also includes a water outlet component. Further, the water outlet component is connected to the mixing valve 20 to discharge the mixed water to the user end. The water outlet component may include, but is not limited to, a water outlet element such as a faucet or shower head; of course, the water outlet component may also not include a water outlet element, and users can configure suitable faucets, shower heads, etc., according to their own needs.

[0087] Optionally, the water outlet assembly includes a first pipeline and a first pump body. One end of the first pipeline is connected to the mixing valve 20, and the other end of the first pipeline is connected to the water-using end. The first pump body is disposed on the first pipeline. It is understood that by providing the first pump body, the water mixed by the mixing valve 20 can be pumped along the first pipeline to the water-using end, providing a strong water flow and improving the cleaning capacity of the cleaning machine. Furthermore, a water outlet fitting can be installed at the outlet end of the first pipeline for user convenience.

[0088] In one embodiment, the cleaning machine 100 further includes a drainage component connected to the first pipeline. The cleaning machine 100 is used to discharge the remaining water after washing through the drainage component. It is understood that after the cleaning machine 100 finishes washing, water remains in the first and second water chambers of the water storage container, and water also remains in the first pipeline of the water outlet component. If the cleaning machine 100 is not used for a long time, the water remaining in the water chambers and pipelines is prone to bacterial growth and corrosion of the container and pipelines, affecting the service life of the cleaning machine 100. Therefore, the cleaning machine 100 in this solution is equipped with a drainage component connected to the first pipeline. The remaining water in the first and / or second water chambers after washing can flow into the first pipeline, and the remaining water in the first pipeline can flow through the discharge component and be discharged outwards, thereby realizing the function of the cleaning machine 100 in discharging the remaining water after washing and improving the reliability and service life of the cleaning machine 100.

[0089] See Figure 2 , Figure 3As shown, in one embodiment, the water storage container 10 includes a container body and a mounting part 11. The mounting part 11 protrudes from the container body and has a mounting channel 111. The mixing valve 20 is inserted into the mounting channel 111, and the valve fixing member 40 is detachably mounted on the mounting part 11.

[0090] In the above embodiment, the mounting part 11 can be a boss provided on the outer surface of the water storage container 10, and the mounting channel 111 is provided through the boss and connects the first water cavity and the second water cavity of the container body respectively. When the mixing valve 20 is inserted into the mounting channel 111, the connection is achieved by the insertion and cooperation of the valve body 21 of the mixing valve 20 with the mounting channel 111. A sealing ring structure can be provided on the outer periphery of the valve body 21. When the valve body 21 is inserted and installed in the mounting channel 111, the sealing ring structure is provided between the valve body 21 and the mounting channel 111, which can limit the deflection of the valve body 21 relative to the mounting channel 111. After the mixing valve 20 is installed, the valve fixing member 40 can be connected and fixed with the mounting part 11. The valve fixing member 40 and the mixing valve 20 can limit the deflection of the valve body 21 through the cooperation of the limiting plane 411 and the mating plane 211. Therefore, when the mixing valve 20 and the valve fixing member 40 are assembled onto the water storage container 10, the function of limiting the deflection of the valve body 21 of the mixing valve 20 can be achieved.

[0091] In other embodiments, the mixing valve 20 can also be located outside the water storage container 10. The specific installation location is not limited, as long as the mixing valve 20 can communicate with both the first and second water chambers. The mixing valve 20 can be a mechanical thermostatic valve or an electronic thermostatic valve; the specific configuration can be determined as needed and is not limited here. By setting the mixing valve 20, the hot water in the first water chamber and the room-temperature water in the second water chamber can be mixed according to usage requirements to meet the user's water temperature needs.

[0092] When the mixing valve 20 is inserted into the installation channel 111, a mating structure can be provided between the valve body 21 and the installation channel 111 to prevent over-insertion of the valve body 21. (See reference...) Figure 10 As shown, optionally, the valve body 21 of the mixing valve 20 has a raised edge 212 on its outer periphery, and the inner wall of the mounting channel 111 has a stepped surface 111a, which abuts against the raised edge 212. This arrangement prevents the valve body 21 of the mixing valve 20 from being over-inserted.

[0093] See Figure 3 , Figure 6 As shown, in one embodiment, the mounting part 11 has a positioning hole 112 on its periphery, and the valve fixing member 40 has a positioning part 42 on the side facing the mounting part 11. The positioning part 42 has a positioning protrusion 421 that is positioned and engaged with the positioning hole 112.

[0094] In the above embodiment, the positioning hole 112 can penetrate from the outer surface of the mounting part 11 into the mounting channel 111. The number of positioning holes 112 can be set to one, two, three, etc. When the valve fixing member 40 is installed towards the mounting part 11, the positioning part 42 can be inserted into the mounting channel 111, and the positioning protrusion 421 of the positioning part 42 can be inserted into the positioning hole 112 from the inside of the mounting channel 111, so that the valve fixing member 40 can be connected and fixed with the mounting part 11.

[0095] When assembling the valve fixing member 40 onto the mounting part 11, to improve the installation firmness of the valve fixing member 40 on the mounting part 11, optionally, a limiting groove 113 is provided along the edge of the mounting channel 111, and a positioning rib 43 is provided on the side of the valve fixing member 40 facing the mounting part 11, which is inserted and engaged with the limiting groove 113. With this configuration, when the valve fixing member 40 is installed onto the mounting channel 111, it can be fixed not only by the insertion and engagement of the positioning protrusion 421 with the positioning hole 112, but also by the insertion and engagement of the positioning rib 43 with the limiting groove 113, thereby improving the firmness and stability of the valve fixing member 40 in the mounting part 11.

[0096] In this invention, two limiting grooves 113 can be provided, with the two limiting grooves 113 arranged opposite to each other. Similarly, two positioning holes 112 can be provided, with the two positioning holes 112 arranged opposite to each other. Furthermore, the two limiting grooves 113 and the two positioning holes 112 can be staggered sequentially. Thus, when the valve fixing member 40 is connected and fixed to the mounting part 11, the connection position between the valve fixing member 40 and the mounting part 11 can be evenly distributed, resulting in a more stable connection between the valve fixing member 40 and the mounting part 11.

[0097] In this invention, after the valve fixing member 40 is assembled onto the mounting part 11, in order to ensure that the second limiting structure on the valve fixing member 40 can correctly cooperate with the rotary adjustment component 30, the limiting groove 113 can be configured as a first limiting groove 113a and a second limiting groove 113b with unequal groove widths. The positioning rib 43 can be configured as a first positioning rib 431 that inserts into the first limiting groove 113a, and a second positioning rib 432 that inserts into the second limiting groove 113b. When the valve fixing member 40 is installed onto the mounting part 11, misalignment of the valve fixing member 40 can be avoided, preventing the second limiting structure from effectively cooperating with the rotary adjustment component 30. The relevant settings are as follows.

[0098] See Figure 3 , Figure 6As shown, optionally, the limiting groove 113 includes a first limiting groove 113a and a second limiting groove 113b, the width of the first limiting groove 113a is greater than the width of the second limiting groove 113b, and the positioning rib 43 includes a first positioning rib 431 and a second positioning rib 432, the first positioning rib 431 is inserted into the first limiting groove 113a, and the second positioning rib 432 is inserted into the second limiting groove 113b.

[0099] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
