[0061] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0062] It should be noted that all directional indications in the embodiments of the present application (such as up, down, left, right, front, back, etc.) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0064] In addition, in this application, descriptions such as "first", "second", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of technical features indicated. Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in this field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by this application.

[0065] The present application proposes a range hood, which includes a smoke collection module 100, wherein the smoke collection module 100 includes a liquid storage module 1000 and a main body, the liquid storage module 1000 includes a frame 1100, an oil collecting box 1200, a water box 1300, a hinge 1400 and a cover panel 1500, the frame 1100 is installed to the main body, and the frame 1100 has a first cavity 1110 and a second cavity 1120, the first cavity 1110 is used for the oil collecting box 1200 to be installed therein, and the second cavity 1120 is used for the water box 1300 to be installed therein, the hinge 1400 is installed on the frame 1100, and is used to be connected to the cover panel 1500, under the action of the hinge 1400, the cover panel 1500 can be rotated to reveal and cover the oil collecting box 1200 and the water box 1300. The frame 1100, the oil collecting box 1200, the water box 1300, the hinge 1400 and the covering panel 1500 are connected to form the liquid storage module 1000. The modular design can improve the efficiency of assembly and disassembly, which is not only conducive to assembly in the factory stage, but also in the later maintenance or cleaning, only the connection between the frame 1100 and the main body needs to be released to disassemble the entire liquid storage module 1000, which is convenient for cleaning and maintenance.

[0066] Specifically, the range hood includes a smoke collecting module 100 and an exhaust module 200. Figure 1 , Figure 3 and Figure 5As shown, the exhaust module 200 is installed above the smoke collection module 100. The smoke collection module 100 is used to gather the oil smoke, and the exhaust module 200 is used to provide power for exhaust air. Generally speaking, the exhaust module 200 has a fan. When the fan is working, the oil smoke first enters the smoke collection module 100 and then is transmitted to the exhaust module 200, and is finally discharged to the outside through the fan.

[0067] The smoke collecting module 100 includes a liquid storage module 1000 and a main body. The main body constitutes most of the structure of the smoke collecting module 100. For example, the main body includes a top plate 2210, a rear plate (not shown in the figure), a side plate 2220 and a bottom plate 2240. The so-called front, back, left and right directions are based on the installation of the range hood in the kitchen. The side of the range hood facing the user is the front, the side away from the user is the back, the side corresponding to the user's left hand is the left, and the side corresponding to the right hand is the right. The top plate 2210 has an opening (not shown in the figure), and the exhaust module 200 is installed at the opening of the top plate 2210. Along the roughly horizontal direction, the top plate 2210 has a larger size relative to the exhaust module 200 to increase the smoke collecting range of the smoke collecting module 100. Side panels 2220 are provided on both sides of the top panel 2210, and the back panel is located behind the top panel 2210 and the side panels 2220. The top panel 2210 and the back panel can be formed by bending the same panel, and then the side panels 2220 are connected thereto, or the top panel 2210 and the side panels 2220 are formed by bending the same panel, and then the back panel is connected thereto, or the back panel and the side panels 2220 are formed by bending the same panel, and then the top panel 2210 is connected thereto. The bottom panel 2240 is connected to the bottom ends of the back panel and the side panels 2220. Through the cooperation of the top panel 2210, the back panel, the side panels 2220 and the bottom panel 2240, the smoke collecting module 100 is roughly triangular when viewed from the left or right side.

[0068] Combination Figure 2As shown, the main body also includes a guide plate 2250, which is located in front of the rear plate and is arranged between the side plates 2220 on the left and right sides. The guide plate 2250 is provided with an air inlet 2251. The top plate 2210, the side plates 2220, the rear plate and the guide plate 2250 enclose a larger internal space, and the oil smoke enters the internal space from the air inlet 2251 and then enters the exhaust module 200. Generally speaking, the smoke collecting module 100 also includes a control panel 2410, an upper panel 2420 and an opening and closing panel 2430, which are arranged from top to bottom and arranged at the front end of the smoke collecting module 100, and together form a shield for the guide plate 2250. The control panel 2410 realizes the control of the range hood, and the range hood can be turned on and off, function selection, and operation parameter display can be realized through the control panel 2410. The upper panel 2420 is arranged between the control panel 2410 and the opening and closing panel 2430, and is arranged in accordance with the shape of the smoke collecting module 100. The opening and closing panel 2430 is configured to be movable (for example, by being driven by a driving mechanism), so that the air inlet 2251 can be opened and closed. When the range hood is needed, the opening and closing panel 2430 is movable to open the air inlet 2251, so as to extract the oil smoke. When the range hood is not needed, the opening and closing panel 2430 is movable to close the air inlet 2251. Generally speaking, the opening and closing panel 2430 can open and close the air inlet 2251 by rotating. Of course, the opening and closing panel 2430 can also open and close the air inlet 2251 by other means.

[0069] During the process of the range hood sucking oil smoke, the oil mist particles in the oil smoke will adhere to the corresponding parts wherever they pass through to form oil stains. The oil stains flow downward under the action of gravity. In addition, when the range hood is steam cleaned, the condensed water formed will also flow downward. In order to facilitate the collection of oil stains and condensed water, it is necessary to set an oil collection box 1200 at the lower position of the range hood. It can be understood that the so-called oil collection box 1200 is a component for collecting dirt, such as the oil stains and condensed water mentioned above. The following only takes oil stains as an example. As mentioned above, the range hood can be steam cleaned, so water needs to be provided. The water is turned into high-temperature steam through the action of the steam generator. The high-temperature steam is sprayed to the impeller of the fan, thereby playing a cleaning role. In order to facilitate the addition of water, a water box 1300 will be set at the lower position of the range hood. Therefore, the liquid storage module 1000 in this embodiment is set at the lower position of the range hood.

[0070] Combination Figures 1 to 5As shown, the liquid storage module 1000 includes a frame 1100, an oil collecting box 1200, a water box 1300, a hinge 1400 and a cover panel 1500. The frame 1100 serves as the skeleton of the liquid storage module 1000 and supports and installs other components of the liquid storage module 1000. The frame 1100 forms a first cavity 1110 and a second cavity 1120. The first cavity 1110 realizes the installation of the oil collecting box 1200, and the second cavity 1120 realizes the installation of the water box 1300. The first cavity 1110 and the second cavity 1120 are arranged in the left-right direction. The structural form of the oil collecting box 1200 is not limited, as long as it can collect the oil, for example, the oil collecting box 1200 is open upward to facilitate the collection of oil, and the structural form of the water box 1300 is also not limited, for example, the first cavity 1110 and the second cavity 1120 are both open to the front, the oil collecting box 1200 can be inserted into the first cavity 1110 from front to back, and the water box 1300 can be inserted into the second cavity 1120 from front to back. The hinge 1400 is a component used to connect the frame 1100 and the cover panel 1500, so that the cover panel 1500 can rotate relative to the frame 1100. This embodiment does not limit the structural form of the hinge 1400. The covering panel 1500 is used to cover the frame 1100, the oil collecting box 1200, the water box 1300 and the hinge 1400 to improve the aesthetics. For example, when it is necessary to clean the oil collecting box 1200 or add water to the water box 1300, the covering panel 1500 needs to be rotated to expose the oil collecting box 1200 and the water box 1300 so that the user can take and put them. When it is not necessary to clean the oil collecting box 1200 or add water to the water box 1300, the covering panel 1500 is rotated (reset) to cover the oil collecting box 1200 and the water box 1300 to improve the aesthetics. For example, when the covering panel 1500 is in a state of shielding the water box 1300 and the oil collecting box 1200, it is located below the opening and closing panel 2430, and the covering panel 1500 rotates downward to expose the water box 1300 and the oil collecting box 1200, and the user can take out the water box 1300 and the oil collecting box 1200, and the covering panel 1500 rotates upward to shield the water box 1300 and the oil collecting box 1200, thereby improving the aesthetics.

[0071] Since the frame 1100 is installed on the main body, and the oil collecting box 1200, the water box 1300, the hinge 1400 and the covering panel 1500 are installed on the frame 1100, the connection between the frame 1100 and the main body can be achieved, and the connection between the liquid storage module 1000 and the main body can be achieved. The separation of the liquid storage module 1000 and the main body can be achieved by releasing the connection between the frame 1100 and the main body. In other words, the frame 1100, the oil collecting box 1200, the water box 1300, the hinge 1400 and the covering panel 1500 form a large module (liquid storage module 1000), which is more conducive to cleaning and maintenance.

[0072] For example, after the range hood has been used for a period of time, if the hinge 1400 fails and the cover panel 1500 cannot rotate smoothly, it needs to be repaired. Since the range hood is installed at a certain height, it will be inconvenient for the operator to perform maintenance at a certain height. In this embodiment, as long as the connection between the frame 1100 and the main body is released, the entire liquid storage module 1000 can be disassembled and placed on the work surface, so that the rotation failure of the cover panel 1500 can be easily repaired, and the corresponding components can also be easily disassembled and replaced during the maintenance process.

[0073] For another example, after the range hood has been used for a period of time, the entire liquid storage module 1000 will become dirty, especially the position where the hinge 1400 is located. Cleaning the liquid storage module 1000 at a certain height will also bring various inconveniences. Therefore, in this embodiment, as long as the connection between the frame 1100 and the main body is released, the entire liquid storage module 1000 can be disassembled for cleaning, which is convenient and quick, and improves the user experience.

[0074] Combination Figure 1 , Figure 3 and Fig. 9 As shown, in some embodiments of the present application, in order to facilitate the connection and disassembly between the frame 1100 and the main body, the frame 1100 is connected to the main body through its outer edge 1130, and the covering panel 1500 can shield and reveal the outer edge 1130 of the frame 1100.

[0075] Specifically, the outer edge 1130 of the frame 1100 is the peripheral part of the frame 1100. The outer edge 1130 of the frame 1100 surrounds the first cavity 1110 and the second cavity 1120. The frame 1100 can be fixed to the main body by connecting the outer edge 1130 to the main body. It can be understood that there are many ways to connect the outer edge 1130 to the main body. As long as the frame 1100 is effectively fixed to the main body, the most appropriate way can be selected, such as fastening the outer edge 1130 to the main body with screws. In this embodiment, the cover panel 1500 can expose the outer edge 1130 of the frame 1100, which is convenient for disassembly and assembly. For example, when the liquid storage module 1000 needs to be disassembled, the cover panel 1500 can be rotated to expose the water box 1300 and the oil collecting box 1200. At this time, the cover panel 1500 simultaneously realizes the exposure of the outer edge 1130, so that the operator can intuitively observe the outer edge 1130, thereby facilitating the operation and releasing the connection between the outer edge 1130 and the main body. It can be understood that in most cases, the cover panel 1500 is in a state of shielding the water box 1300 and the oil collecting box 1200. At this time, the cover panel 1500 also realizes the shielding of the outer edge 1130. Since there is a connection point between the outer edge 1130 and the main body, the shielding of the cover panel 1500 improves the aesthetics.

[0076] Combination Figure 3 , Figure 5 , Figure 6 and Figure 8 As shown, in some embodiments of the present application, the main body has a receiving cavity 2300 . By setting the receiving cavity 2300 , the frame 1100 is effectively constrained and the installation stability of the frame 1100 is improved.

[0077] Specifically, the so-called accommodating cavity 2300 is a space with a certain depth. For example, the main body has an oil retaining groove 2260. The so-called oil retaining groove 2260 is used to receive the oil dirt flowing from top to bottom. The oil retaining groove 2260 is arranged below the guide plate 2250, between the rear plate and the side plates 2220 on opposite sides. The cover panel 1500 can also shield the oil retaining groove 2260. The oil retaining groove 2260 is located above the bottom plate 2240, so that the accommodating cavity 2300 is enclosed by the rear plate and the side plates 2220 on opposite sides. The frame 1100 can be embedded in the accommodating cavity 2300, so that the frame 1100 can be initially positioned, which is more convenient for the subsequent connection means to achieve the connection and fastening between the frame 1100 and the main body. Since the oil collecting box 1200 will store a certain amount of oil and the water box 1300 will store a certain amount of water, the oil collecting box 1200 and the water box 1300 have a certain weight. The frame 1100 is embedded in the accommodating cavity 2300, so the frame 1100 is at least partially covered by the cavity wall of the accommodating cavity 2300, that is, by the main body. This can effectively support the oil collecting box 1200 and the water box 1300, and improve the installation stability of the oil collecting box 1200 and the water box 1300.

[0078] The oil blocking groove 2260 is surrounded and arranged above the accommodating cavity 2300, that is, located above the oil collecting box 1200. An oil leakage hole 2261 is arranged on the oil blocking groove 2260. The oil leakage hole 2261 is located above the oil collecting box 1200. The oil gathers in the oil blocking groove 2260 and flows toward the oil leakage hole 2261. Under the action of gravity, the oil falls into the oil collecting box 1200 through the oil leakage hole 2261.

[0079] Combination Figure 24 to Figure 27 As shown, in some embodiments of the present application, the hinge 1400 includes a connecting shaft 1420, a first connecting arm 1430 and an elastic member 1450, the first connecting arm 1430 is arranged on the connecting shaft 1420, and the first connecting arm 1430 is configured to be rotatable, and the elastic member 1450 is used to generate force on the first connecting arm 1430, so that the first connecting arm 1430 can rotate toward the frame 1100.

[0080] Specifically, the connecting shaft 1420 is used to support the first connecting arm 1430, and the first connecting arm 1430 is arranged on the connecting shaft 1420. There are many ways to rotatably arrange the first connecting arm 1430, for example, the first connecting arm 1430 and the connecting shaft 1420 are rotatably connected, and for another example, the first connecting arm 1430 and the connecting shaft 1420 are not rotatably connected, but the connecting shaft 1420 is designed to be rotatable, so that the first connecting arm 1430 can drive the connecting shaft 1420 to rotate. The cover panel 1500 is connected to the first connecting arm 1430 to support the cover panel 1500 and make the cover panel 1500 rotatable.

[0081] For example, combined with Figure 1 , Figure 3 and Figure 4 As shown, when the cover panel 1500 is rotated downward, the cover panel 1500 drives the first connecting arm 1430 to rotate downward, that is, at this time, the first connecting arm 1430 rotates away from the frame 1100, and the cover panel 1500 moves away from the frame 1100 so that the water box 1300 and the oil collecting box 1200 are exposed. When the cover panel 1500 is rotated upward, the cover panel 1500 drives the first connecting arm 1430 to rotate upward, and at this time, the first connecting arm 1430 rotates toward the frame 1100, so that the cover panel 1500 assembly is close to the frame 1100 and shields the water box 1300 and the oil collecting box 1200, and at this time, the cover panel 1500 can be abutted against the frame 1100.

[0082] It is understandable that the covering panel 1500 needs to be in a state of shielding the water box 1300 and the oil collecting box 1200 most of the time. To this end, in this embodiment, an elastic member 1450 is provided. The elastic member 1450 needs to generate a force on the first connecting arm 1430, and the force forces the first connecting arm 1430 to rotate toward the frame 1100, so that the covering panel 1500 shields the water box 1300 and the oil collecting box 1200. It is understandable that the force applied by the elastic member 1450 to the first connecting arm 1430 needs to overcome the gravity of the covering panel 1500 so that the covering panel 1500 can maintain the state of shielding the water box 1300 and the oil collecting box 1200.

[0083] For example, the user applies force to the cover panel 1500, driving the cover panel 1500 to rotate downward, and the cover panel 1500 drives the first connecting arm 1430 to rotate downward and away from the frame 1100. During the rotation of the first connecting arm 1430, the elastic member 1450 undergoes elastic deformation and accumulates elastic potential energy. When the user cancels the force applied to the cover panel 1500, the elastic member 1450 releases the elastic potential energy, generating a force for the first connecting arm 1430 to rotate toward the frame 1100, so that the first connecting arm 1430 rotates upward and toward the frame 1100, driving the cover panel 1500 to rotate to shield the water box 1300 and the oil collecting box 1200.

[0084] The elastic member 1450 can be set at multiple positions as long as it can generate force on the first connecting arm 1430 so that the first connecting arm 1430 rotates toward the frame 1100. For example, the elastic member 1450 is a torsion spring, which is mounted on the connecting shaft 1420. One end of the elastic member 1450 is fixed, and the other end of the elastic member 1450 is connected to the first connecting arm 1430. In this way, the first connecting arm 1430 can drive the elastic member 1450 to elastically deform, and the elastic member 1450 can also drive the first connecting arm 1430 to rotate.

[0085] The cover panel 1500 is connected to the hinge 1400 by the following scheme: Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 as well as Figure 20 to Figure 23 As shown, in some embodiments of the present application, the cover panel 1500 is provided with a second connecting arm 1700, and the second connecting arm 1700 is connected to the first connecting arm 1430 to realize the connection between the cover panel 1500 and the hinge 1400. It can be understood that in order to enable the cover panel 1500 to maintain the state of shielding the water box 1300 and the oil collecting box 1200 when no force is applied by the user, when the hinge 1400 is assembled to the frame 1100 and the cover panel 1500 is not installed, the elastic member 1450 will drive the first connecting arm 1430 to rotate toward the frame 1100, so that the first connecting arm 1430 is extremely close to the frame 1100. Under the premise that the first connecting arm 1430 is extremely close to the frame 1100, it will cause difficulty in connecting the first connecting arm 1430 and the second connecting arm 1700, that is, it will cause difficulty in installing the cover panel 1500.

[0086] To this end, in this embodiment, the second connecting arm 1700 has a guide plate 1710, and the guide plate 1710 is arranged at an angle relative to the cover panel 1500. Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 as well as Figure 20 to Figure 23 As shown, the guide plate 1710 is arranged to be inclined downward relative to the cover panel 1500. When the cover panel 1500 and the hinge 1400 are connected, the cover panel 1500 drives the second connecting arm 1700 to move toward the first connecting arm 1430, and the guide plate 1710 of the second connecting arm 1700 and the first connecting arm 1430 are abutted together. As the cover panel 1500 moves (rotates) further, under the guiding action of the guide plate 1710, it is equivalent to that the first connecting arm 1430 is hooked by the guide plate 1710. The guide plate 1710 can drive the first connecting arm 1430 to rotate away from the frame 1100, so that the first connecting arm 1430 and the second connecting arm 1700 are in an exposed state, thereby facilitating the operator to connect and fix the first connecting arm 1430 and the second connecting arm 1700. In this way, manpower can be saved, and a single person can also efficiently install the cover panel 1500.

[0087] Furthermore, combined with Figure 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 as well as Figure 20 to Figure 23As shown, in some embodiments of the present application, the second connecting arm 1700 also has a connecting plate 1720, and the guide plate 1710 is arranged to intersect with the connecting plate 1720. The connecting plate 1720 is used to achieve overlap with the first connecting arm 1430 under the premise that the first connecting arm 1430 and the second connecting arm 1700 are in place with each other. The connecting plate 1720 and the first connecting arm 1430 are overlapped to form a double-layer structure, which improves the structural strength and makes the connection between the first connecting plate 1720 and the first connecting arm 1430 have higher stability.

[0088] Specifically, when the cover panel 1500 and the hinge 1400 are connected, the cover panel 1500 drives the second connecting arm 1700 to move toward the first connecting arm 1430, and the guide plate 1710 of the second connecting arm 1700 abuts against the first connecting arm 1430. As the cover panel 1500 moves further, under the guidance of the guide plate 1710, the guide plate 1710 drives the first connecting arm 1430 to rotate away from the frame 1100 until the first connecting arm 1430 and the second connecting arm 1700 are mutually abutted. When the connection is in place, the connection plate 1720 is overlapped with the first connection arm 1430, and the overlap of the connection plate 1720 and the first connection arm 1430 forms a double-layer reinforcement structure, which lays a foundation for the connection between the first connection plate 1720 and the first connection arm 1430. The double-layer reinforcement structure ensures that the connection between the first connection plate 1720 and the first connection arm 1430 is more stable, that is, the first connection arm 1430 and the second connection arm 1700 are stably connected, so that the installation of the cover panel 1500 is more stable. It can be understood that there are many ways to connect the first connection plate 1720 and the first connection arm 1430, for example, the first connection plate 1720 and the first connection arm 1430 are fastened with screws.

[0089] Combination Figure 20 to Figure 23 As shown, in some embodiments of the present application, the second connecting arm 1700 further has a base 1730, and the second connecting arm 1700 is fixed to the cover panel 1500 through the base 1730. For example, the base 1730 is connected to the cover panel 1500 by means of adhesive. Of course, the base 1730 can also be connected to the cover panel 1500 by other means. Since the second connecting arm 1700 needs to be connected to the first connecting arm 1430, that is, when the cover panel 1500 is installed in place, the second connecting arm 1700 needs to support the weight of the cover panel 1500. In order to make the connection between the second connecting arm 1700 and the cover panel 1500 more stable, the base 1730 extends along the up and down direction of the cover panel 1500, thereby increasing the contact area between the second connecting arm 1700 and the cover panel 1500 and ensuring effective support for the cover panel 1500.

[0090] The connecting plate 1720 is arranged on the base 1730, for example, the guide plate 1710, the connecting plate 1720 and the base 1730 are integrally formed and prepared by a bending process, and have a high structural strength. The guide plate 1710, the connecting plate 1720 and the base 1730 are surrounded by a slot 1740. When the guide plate 1710 and the first connecting arm 1430 are in contact, as the cover panel 1500 moves further, the first connecting arm 1430 will be inserted into the slot 1740. When the first connecting arm 1430 is inserted into the limit position of the slot 1740, the first connecting arm 1430 and the second connecting arm 1700 restrict each other, indicating that the cover panel 1500 has been installed in place, which is convenient for the subsequent further tightening connection between the first connecting arm 1430 and the second connecting arm 1700.

[0091] When installing the cover panel 1500, the first connecting arm 1430 needs to be inserted into the slot 1740 so as to cooperate with the second connecting arm 1700. In order to facilitate the insertion of the first connecting arm 1430, the first connecting arm 1430 is inserted into the slot 1740. Figure 7 As shown, in some embodiments of the present application, the first connecting arm 1430 has a tip portion 1431 , and when the cover panel 1500 is installed, the tip portion 1431 is more likely to abut against the guide plate 1710 , thereby being inserted into the slot 1740 under the action of the guide plate 1710 .

[0092] In some embodiments of the present application, the hinge 1400 includes a hinge seat 1410 , which is disposed on the frame 1100 . The hinge seat 1410 extends in the up-and-down direction of the frame 1100 , and the connecting shaft 1420 is disposed on the hinge seat 1410 .

[0093] Specifically, the hinge seat 1410 and the frame 1100 are overlapped and connected to enhance the structural strength. Since the hinge 1400 is installed on the frame 1100 and needs to be connected to the cover panel 1500, a large weight will be applied to the frame 1100. In order to prevent the frame 1100 from deforming, the hinge seat 1410 and the frame 1100 are overlapped and connected, and the hinge seat 1410 extends in the up and down direction to ensure the contact area with the frame 1100 and maintain high stability. The connecting shaft 1420 is set on the hinge seat 1410. For example, the connecting shaft 1420 and the hinge seat 1410 are relatively non-rotatable, and the first connecting arm 1430 needs to be rotatably connected to the connecting shaft 1420.

[0094] Furthermore, in order to prevent the first connecting arm 1430 from rotating excessively, Figure 24 to Figure 27As shown, the hinge 1400 also includes a stopper 1440 , which includes two stoppers 1440 , one of which is used to limit the rotation angle of the first connecting arm 1430 away from the frame 1100 , and the other stopper 1440 is used to limit the rotation angle of the first connecting arm 1430 toward the frame 1100 .

[0095] In some embodiments of the present application, in order to facilitate the addition of water to the water box 1300, the water box 1300 has a water addition port 1330. When the water box 1300 needs to be added with water, the user needs to remove the water box 1300 from the second cavity 1120. Also, when the water box 1300 is installed in the second cavity 1120, water needs to be provided for steam cleaning. Therefore, how to ensure that the water box 1300 can provide steam water while being disassembled and assembled becomes the key.

[0096] Combination Figures 9 to 12 as well as Fig.16 and Fig.17 As shown, in this embodiment, the water box 1300 also has a water absorption hole 1310, and the liquid storage module 1000 also includes a water joint 1600, which is arranged on the frame 1100, and the water joint 1600 has a water passage 1620, and the water joint 1600 is arranged on the frame 1100. When the water box 1300 is disassembled to add water, it is not necessary to disassemble the water joint 1600, that is, the water joint 1600 remains in the current position, and when the water box 1300 is reassembled after adding water, the water joint 1600 is not removed. When the second cavity 1120 is opened, the water box 1300 is installed in a preset position, that is, it cooperates with the water connector 1600. The water connector 1600 abuts against the periphery of the water suction hole 1310 to form a seal, thereby realizing the connection between the water suction hole 1310 and the water passage 1620. The other end of the water connector 1600 needs to be connected to a water suction pump. When the water suction pump is working, the water in the water box 1300 can be transported to the water suction pump through the water suction hole 1310 and the water passage 1620. The water suction pump transports the water to the steam generator to generate steam.

[0097] Combination Fig.15 , Fig.18 and Fig.19 As shown, in order to facilitate the suction of water in the water box 1300, a water suction hole 1310 is set at the top of the water box 1300, and a water suction pipe 1320 is set inside the water box 1300. One end of the water suction pipe 1320 is connected to the water suction hole 1310, and the other end of the water suction pipe 1320 extends to the bottom of the water box 1300. When the water joint 1600 and the periphery of the water suction hole 1310 are abutted, the water suction pump can achieve suction, and water is transported from the bottom of the water box 1300 through the water suction pipe 1320, the water suction hole 1310 and the water passage 1620 to the water suction pump. Of course, the water suction channel can be inserted with a pipeline 1640, and the water suction pump is connected to the pipeline 1640.

[0098] Furthermore, since the abutment between the water connector 1600 and the periphery of the water absorption hole 1310 is achieved during the process of inserting the water box 1300 into the second cavity 1120, in this embodiment, the water connector 1600 is designed to be able to achieve elastic deformation. For example, the water connector 1600 is made of rubber material. When the water box 1300 is inserted into the second cavity 1120 to a preset position, the periphery of the water absorption hole 1310 forces the water connector 1600 to undergo elastic deformation, thereby achieving a close combination of the water connector 1600 and the periphery of the water absorption hole 1310, achieving effective sealing, and allowing the water passage 1620 to communicate with the water absorption hole 1310.

[0099] When the water box 1300 is inserted into the preset position of the second cavity 1120, the water connector 1600 undergoes elastic deformation. That is, when the water box 1300 has not yet been inserted into the second cavity 1120, part of the water connector 1600 occupies the position of the water box 1300. In this way, when the water box 1300 is inserted into the preset position of the second cavity 1120, the water connector 1600 can be squeezed to make the water connector 1600 undergo elastic deformation. That is to say, during the insertion of the water box 1300, the water box 1300 will generate force on the water connector 1600. In order to prevent the water connector 1600 from deviating or detaching from the frame 1100, the water box 1300 is combined with the water connector 1600 to prevent the water connector 1600 from deviating or detaching from the frame 1100. Fig.13 and Fig.14 As shown, the frame 1100 has a through hole 1121, which is communicated with the second cavity 1120. The water connector 1600 is installed in the through hole 1121, so that a part of the water connector 1600 protrudes into the second cavity 1120. The part of the water connector 1600 protruding into the second cavity 1120 is defined as the boss portion 1610. The periphery of the boss portion 1610 is provided with a guide slope 1611, and the guide slope 1611 is arranged toward the water box 1300. When the water box 1300 is inserted into the second cavity 1120, it will contact the guide slope 1611. Under the action of the guide slope 1611, the water box 1300 forces the boss portion 1610 to be compressed. By providing the guide slope 1611, the force applied by the water box 1300 to the boss portion 1610 makes it easier to compress the boss portion 1610, thereby preventing the entire water connector 1600 from being separated from the through hole 1121.

[0100] In order to effectively install the water connector 1600 into the through hole 1121, Fig.13 , Fig.14 and Fig.15As shown, a card slot 1630 is provided around the water connector 1600. When the water connector 1600 passes through the through hole 1121, the card slot 1630 is aligned with the edge of the through hole 1121 and inserted, thereby realizing the installation of the water connector 1600. In this way, the water connector 1600 is constrained in the axial direction of the through hole 1121. When the water box 1300 generates a force on the water connector 1600 to deform the water connector 1600, the direction of the force generated by the water box 1300 on the water connector 1600 is roughly in the same direction as the axial direction of the through hole 1121, thereby ensuring that the water connector 1600 will not separate from the through hole 1121 when subjected to force.

[0101] Furthermore, combined with Fig.14 As shown, in some embodiments of the present application, the perforation 1121 is arranged at the corner position of the frame 1100, so that the water connector 1600 can be conveniently clamped into the perforation 1121. It can be understood that since the water connector 1600 needs to be clamped at the edge of the perforation 1121 through the clamping groove 1630 and cannot be separated from the perforation 1121 along the axial direction of the perforation 1121, that is, along the radial direction of the perforation 1121, the water connector 1600 needs to cover the perforation 1121, that is, the water connector 1600 is larger than the perforation 1121. In order to facilitate the installation of the water connector 1600, the perforation 1121 is arranged at the corner position of the frame 1100, so that the water connector 1600 can be inserted by aligning the clamping groove 1630 with the edge of the perforation 1121. The so-called corner position, that is, for example, a through hole 1121 is formed between the top wall and the side wall of the frame 1100, a part of the through hole 1121 is arranged on the top wall, and the other part is arranged on the side wall, so that the water connector 1600 can be conveniently inserted at the corner position, and the slot 1630 is arranged on the edge of the through hole 1121 corresponding to the top wall, which is convenient and quick, and does not require excessive deformation during the installation of the water connector 1600, making it difficult to install.
