Description

Technical Field

[0001] The utility model relates to the technical field of household appliances, in particular to a steam cleaning machine. Background Art

[0002] Steam cleaning machines are steam cleaning machines that use high-temperature steam for cleaning. They are mostly used to clean floor oil stains, kitchen walls, stoves, etc. At present, such equipment is generally large in size, inconvenient to store and use, affecting the consumer experience. At the same time, the cleaning machines with armrests are not easy to remove and require professional tools to install and remove.

[0003] Therefore, how to design a steam cleaning machine with a handrail that is easy to install, use and store has become a problem that needs to be solved urgently. Utility Model Content

[0004] The utility model aims to solve at least one of the technical problems existing in the prior art or related technology.

[0005] To this end, a first aspect of the utility model provides a steam cleaning machine.

[0006] In view of this, the first aspect of the utility model proposes a steam cleaning machine, comprising: a steam engine main body; a locking plate, which is arranged on the steam engine main body, a first installation space including a first opening is formed between the locking plate and the steam engine main body, and a first locking structure is arranged on the locking plate; a handle, a second locking structure is arranged on the first end of the handle, the first end of the handle can extend into the first installation space through the first opening, and when the first end of the handle is located in the first installation space, the first locking structure can cooperate with the second locking structure to limit the first end of the handle to the first installation space; a first elastic member, which is arranged on the first end of the handle or in the first installation space, the first elastic member is in a compressed state when the first locking structure cooperates with the second locking structure, and can generate a first force that makes the first locking structure and the second locking structure tightly cooperate.

[0007] The steam cleaning machine provided by the utility model comprises a steam machine body, a locking plate, a handle and a first elastic member. The handle can be fixedly installed on the steam machine body through the locking plate, so that the handle can be installed when the steam cleaning machine is used, so that the steam cleaning machine can be moved by the handle. When the steam cleaning machine needs to be stored, the handle can be removed, so that the overall volume of the steam cleaning machine can be reduced, so that it is convenient to store. At the same time, since the first elastic member is arranged at the first end of the handle or in the first installation space, the deformation of the first elastic member can play a role of buffering and shock absorption when the handle is installed, thereby improving the installation feel of the handle, and after the handle is installed, the elastic force of the first elastic member can make the first locking structure and the second locking structure cooperate more tightly, more stably and reliably, and prevent the first locking structure and the second locking structure from being out of cooperation.

[0008] Specifically, the locking plate is arranged on the steam engine body, so that a first installation space is formed between the locking plate and the steam engine body. When the handle needs to be installed, the first end of the handle can be extended into the first installation space through the first opening, and then an external force can be applied to the handle to clamp the two ends of the handle and the steam engine body to achieve compression of the first elastic member. At the same time, the handle can be fixed by the cooperation of the first locking structure on the locking plate and the second locking structure on the handle. In this way, after the first locking structure and the second locking structure are matched, the rebound force generated by the compression of the first elastic member can make one of the first locking structure and the second locking structure press against the other, so that the first locking structure and the second locking structure can be matched more tightly and stably. In addition, since the first elastic member is elastic, the deformation of the first elastic member can play a buffering and shock-absorbing role when the handle is installed, which also helps to improve the installation feel of the handle. When the handle needs to be removed, the first locking structure and the second locking structure can be disengaged first, and then the handle can be removed. Fixing the handle by means of a locking structure is not only more convenient when installing or removing the handle, without the need to use tools such as wrenches, but this fixing method is also more reliable, thereby improving the reliability of the steam cleaning machine.

[0009] At the same time, the first elastic member can be arranged on the first end of the handle according to actual needs, or can be arranged in the first installation space, as long as the first elastic member can be compressed and deformed by the handle when the handle is installed.

[0010] Among them, in the design where the first elastic member is arranged in the first installation space, when the handle needs to be installed, the first elastic member can be first extended into the first installation space so that the first elastic member abuts against the first installation space, and then the handle continues to be extended into the first installation space, and pressure is applied to the first elastic member through the handle until the first locking structure and the second locking structure can cooperate.

[0011] When the handle and the steam engine body are separated from each other, the first elastic member is in a natural state.

[0012] The steam cleaning machine provided by the utility model may also have the following additional technical features:

[0013] In some technical solutions, optionally, a first installation groove is provided at the first end of the handle, and the first elastic member is at least partially disposed in the first installation groove.

[0014] In this technical solution, the first elastic member is installed on the handle, and the first installation groove provides a receiving space for the first elastic member.

[0015] In some technical solutions, optionally, a first mounting groove is provided at the first end of the handle. The handle includes: a plug, which is provided at the notch of the first mounting groove, and the plug can slide relative to the handle along the depth direction of the first mounting groove, one end of the first elastic member abuts against the plug, and the other end of the first elastic member abuts against the bottom wall of the first mounting groove; wherein the plug slides relative to the handle, so that the first elastic member can switch between a compressed state and a natural state.

[0016] In this technical solution, the first elastic member can be installed on the handle through the first installation groove and the plug. Since the plug can slide up and down relative to the handle, the first elastic member can be compressed by the plug. The plug can not only avoid the problem of easy loss of the first elastic member, but also protect the first elastic member by the plug to prevent the first elastic member from being damaged by foreign objects.

[0017] In some technical schemes, optionally, the plug includes a cover plate, and one end of the first elastic member is abutted against the cover plate; a lug is arranged on the cover plate, the lug can extend into the first mounting groove, and one of a slideway and a slider is arranged on the lug, and the other of the slideway and the slider is arranged on the side wall of the first mounting groove, and the slider is slidably installed in the slideway; the number of the lugs is two, and the two lugs are arranged at a distance from each other.

[0018] In this technical solution, the cover plate is used to realize the supporting installation of the first elastic member. The lug can extend into the first installation groove, so that when the plug slides relative to the handle, the lug can be used to guide the plug to avoid the plug from deviating during sliding. Specifically, the sliding guide of the plug can be realized by the cooperation of the slideway and the slider to ensure the stability of the plug during sliding. There are two lugs, which are spaced apart from each other, and the first elastic member is located between the two lugs.

[0019] In some technical schemes, optionally, a first positioning column is provided on the cover plate, the first positioning column is located between the two lugs, one end of the first elastic member is sleeved and installed on the first positioning column, and a first positioning hole is provided on the first positioning column, and the handle also includes: a second positioning column, which is provided on the bottom wall of the first mounting groove, and a second positioning hole is provided on the second positioning column; a connecting member, one end of the connecting member is installed in the second positioning hole, and the other end of the connecting member is installed in the first positioning hole; the first elastic member includes a first spring, and the first spring is sleeved and installed outside the connecting member.

[0020] In this technical solution, positioning columns are provided on the bottom wall of the first installation groove and on the cover plate, and the connection between the bottom wall of the first installation groove and the plug can be achieved through the positioning columns. The first elastic member includes a first spring. Because springs are relatively common, have good elastic effects, and are not easily damaged, the cost of the first elastic member can be reduced and the service life of the first elastic member can be ensured. At the same time, after the first elastic member is set as the first spring, the first spring can be installed outside the connecting member, so that the deformation of the spring can be guided by the connecting member to avoid the spring from being offset or stuck during the deformation process.

[0021] In some technical solutions, optionally, a retaining rib is provided on the outer side wall of the lug, and the retaining rib can abut against the end of the first end of the handle, that is, the retaining rib can abut against the surface where the notch of the first installation slot is located.

[0022] In this technical solution, the retaining rib abuts against the end of the first end of the handle so that the entire plug cannot completely enter the first installation groove, thereby preventing the spring from being over-compressed and causing the plug to be stuck in the first installation groove.

[0023] In some technical solutions, optionally, the locking plate can move between a first position and a second position. When the locking plate is in the first position, the first locking structure can cooperate with the second locking structure to limit the first end of the handle to the first installation space. When the locking plate is in the second position, the first locking structure is disengaged from the second locking structure.

[0024] In this technical solution, the lock plate is not completely fixed on the steam engine body, and it can move relative to the steam engine body. For example, the lock plate can be rotatably or slidably installed on the steam engine body so that the lock plate can move between the first position and the second position. When the handle needs to be installed on the steam engine body, the lock plate can be placed in the first position, so that the first lock structure can cooperate with the second lock structure to achieve the connection between the handle and the steam engine body. When the handle needs to be removed, the lock plate can be moved to the second position so that the first lock structure and the second lock structure can be released from the cooperation, so that the handle can be easily removed. This setting, when the handle needs to be removed, because the first lock structure and the second lock structure can be separated and matched through the activity of the lock plate, the removal of the handle is relatively labor-saving. Of course, when the handle needs to be installed, the lock plate can also be opened to facilitate the insertion of the handle, so as to achieve the effect of labor-saving.

[0025] Furthermore, a first guide surface is provided on the first locking structure. When the first end of the handle extends into the first installation space from the first opening, the second locking structure can move along the first guide surface from one side of the first locking structure to the other side of the second locking structure and cooperate with the first locking structure.

[0026] In this technical solution, due to the setting of the first guide surface, when installing the handle, it is only necessary to press the handle toward the steam engine body, and the second locking structure can slide smoothly to the other side of the first locking structure under the guidance of the first guide surface and achieve snap-fitting with it. Therefore, by setting the first guide surface, the handle can be installed more smoothly and conveniently, and the user has fewer operation steps, and can basically achieve single-handed operation.

[0027] Furthermore, a second guide surface is provided on the second locking structure, and the second guide surface can guide the second locking structure to enter the first installation space. When the first end of the handle extends from the first opening into the first installation space, the first locking structure can move along the second guide surface until the second locking structure moves from one side of the first locking structure to the other side of the first locking structure and cooperates with the first locking structure.

[0028] In some technical schemes, optionally, the second locking structure includes: a second locking protrusion, which is arranged on the outer wall of the handle, and the end of the first locking protrusion away from the handle extends obliquely from the first end of the handle toward a direction away from the first end of the handle; a second locking groove, which is surrounded by the second locking protrusion and the outer wall of the handle; and the first locking structure includes a first locking protrusion adapted to the second locking groove.

[0029] In this technical solution, the handle and the lock plate are snap-fitted in the form of a hook, and this method can make the snap fit between the handle and the lock plate more stable and not easy to fall off. Furthermore, the first lock protrusion extends obliquely from the first end of the handle in a direction away from the first end of the handle, that is, the first lock protrusion is not completely perpendicular to the handle, and the angle between it and the handle is less than 90°, that is, the edge of the first lock protrusion is tilted, and this structure can further make the snap fit between the handle and the lock plate more stable and not easy to fall off.

[0030] Furthermore, the thickness of the first locking protrusion along the extension direction of the handle gradually decreases from an end close to the handle to an end far from the handle, that is, the cross-section of the first locking protrusion is a triangle.

[0031] Of course, the handle and the locking plate can also be snap-fitted together by means of slots and protrusions.

[0032] In some technical solutions, optionally, the locking plate can move from a first position to a second position during the process of inserting the handle into the first installation space.

[0033] Furthermore, the steam cleaning machine also includes: a second elastic member, both ends of which are respectively connected to the locking plate and the steam engine body, and is used to move the locking plate back to the first position after the locking plate moves from the first position to the second position.

[0034] In this technical solution, the second elastic member can realize the elastic connection between the lock cover plate and the steam engine body, so that when the handle is inserted into the first installation space, the lock plate can move in the direction away from the steam engine body to avoid the handle, so that the second lock structure on the handle can quickly pass through the first lock structure. After the second lock structure passes through the first lock structure, the lock plate can return to the initial position under the action of the second elastic member to ensure that the second lock structure can match the first lock structure.

[0035] In some technical solutions, optionally, the locking plate and the steam engine body further enclose a second installation space, and the second elastic member is located in the second installation space. That is, an independent installation hole is provided for the second elastic member, so that the second elastic member and the handle can be prevented from interfering with each other, making the installation of the handle smoother and less prone to problems.

[0036] In some technical solutions, optionally, the steam engine body includes: a second mounting groove, which is arranged on the side wall of the steam engine body, and the first side of the second mounting groove is provided with an opening, a partition plate, which is arranged on the second side of the second mounting groove, and the second side is the other side arranged opposite to the first side; a locking plate is installed at the second mounting groove; wherein the first mounting space is surrounded by the locking plate, the partition plate, and part of the inner wall of the second mounting groove, and the locking plate, the partition plate, and another part of the inner wall of the second mounting groove surround the second mounting space, and the first mounting space is located inside the second mounting space. The second elastic member is located in the second mounting space.

[0037] In this technical solution, a second mounting groove can be provided on the side wall of the steam engine body, and then one side wall of the second mounting groove is opened, that is, one side wall of the second mounting groove is provided with an opening, so that the first end of the handle can be extended from the opening into the second mounting groove, thereby realizing the installation of the handle. By providing the second mounting groove and arranging the handle in the mounting groove, the handle can be limited by the side wall and the bottom wall of the mounting groove, thereby improving the stability of the installation of the handle. It is understandable that in the actual setting process, the direction of the opening can be set according to the use requirements. For example, when the handle needs to be installed above the steam engine body, the side wall of the second mounting groove close to the top can be opened upward to form an opening, so that the first end of the handle can be extended from the opening formed above into the second mounting groove. Similarly, when the handle needs to be installed at the rear of the steam engine body, the side wall of the second mounting groove close to the rear can be opened backward to form an opening, so that the first end of the handle can be extended from the opening formed at the rear into the second mounting groove.

[0038] The partition plate is arranged in the second installation groove, and a first installation space is formed between the partition plate and the bottom wall of the second installation groove, and a second installation space is formed between the partition plate and the lock plate, so that the second elastic member can be arranged in the second installation space to form a force on the lock plate, so that the first lock structure and the second lock structure are matched. By arranging the partition plate to separate the first installation space from the second installation space, interference between the second elastic member and the handle can be avoided, thereby improving the reliability of the second elastic member arrangement.

[0039] In some technical solutions, optionally, a limiting structure is further provided in the second installation space, and the second elastic member is provided at the limiting structure.

[0040] In this technical solution, a limiting structure can also be set in the second installation space, and the second elastic member can be set at the limiting structure, so as to prevent the second elastic member from moving, thereby improving the reliability and stability of the cooperation between the first locking structure and the second locking structure.

[0041] In some technical solutions, optionally, the second elastic member includes a second spring, the limiting structure includes a limiting platform and a limiting groove; the second spring is arranged in the limiting groove; or the second spring is installed on the limiting platform.

[0042] In this technical solution, the second elastic member includes a second spring, and the limiting structure includes a limiting platform and a limiting groove, so that one end of the second spring can be set in the limiting groove, or one end of the second spring can be installed on the limiting platform, and then the other end of the second spring can be abutted against the lock plate, so that the elastic force generated by the second spring can act on the lock plate, thereby driving the first lock structure to cooperate with the second lock structure. Specifically, the second spring can be in a compressed state when it is set in the second installation space, and then when the other end of the second spring is abutted against the lock plate, the elastic force generated by the second spring can act on the lock plate. Since the spring has good elasticity, large deformation and low cost, it can reduce the overall production cost of the steam cleaning machine and make the equipment easier to assemble.

[0043] In some technical solutions, the locking plate is optionally connected to the steam engine body in a rotational manner, because compared with the sliding connection, the locking plate occupies less space and has a simpler structure.

[0044] In some technical solutions, optionally, one of the rotating shaft and the shaft hole is provided on the locking plate, and the other of the rotating shaft and the shaft hole is provided on the steam engine body, and the locking plate is rotatably arranged on the steam engine body through the cooperation of the rotating shaft and the shaft hole.

[0045] In this technical solution, the action of the lock plate relative to the steam engine body can be rotation or sliding. When the lock plate rotates relative to the steam engine body, one of the rotating shaft and the shaft hole can be set on the lock plate, and the other of the rotating shaft and the shaft hole can be set on the steam engine body, so that the lock plate rotates relative to the steam engine body through the cooperation of the rotating shaft and the shaft hole. The first lock structure cooperates with the second lock structure by rotating, which can reduce the space occupied, facilitate the setting of the lock structure, and has high stability.

[0046] In some technical solutions, optionally, the locking plate rotates in a direction close to and away from the steam engine body.

[0047] In some technical solutions, optionally, the locking plate rotates with a direction away from the steam engine body as the axis.

[0048] In some technical solutions, optionally, the first locking structure is arranged on a side of the locking plate close to the steam engine body; the second locking structure is arranged close to one end of the handle and is arranged opposite to the first locking structure.

[0049] In this technical solution, the first locking structure can be arranged on the locking plate at one side close to the steam engine body, and the second locking structure can be arranged close to one end of the handle and arranged opposite to the first locking structure. In this way, the first locking structure and the second locking structure can form a good match.

[0050] In some technical solutions, optionally, the locking plate is slidably installed on the steam engine body, and the sliding of the locking plate can drive the first locking structure to cooperate with the second locking structure, or drive the first locking structure to disengage from the second locking structure.

[0051] In this technical solution, the locking plate moves relative to the steam engine body by sliding. Specifically, a slide rail can be provided on the steam engine body, and a clamping block can be provided on the locking plate. The clamping block is provided in the slide rail to slide, thereby driving the first locking structure to move, so as to achieve the cooperation between the first locking structure and the second locking structure, or to achieve the disengagement between the first locking structure and the second locking structure.

[0052] In some technical schemes, optionally, there are two locking plates, and the two second locking structures are respectively arranged on two sides of the steam engine body that are opposite to each other; there are two handles, and the two handles are arranged opposite to each other, and each handle is correspondingly provided with a second locking structure and a first elastic member; the two handles are connected by a connecting rod.

[0053] In this technical solution, two locking plates are provided, namely, a first locking plate and a second locking plate, and the first locking plate and the second locking plate are respectively provided on opposite sides of the steam engine body. There are also two handles, and the two handles are connected by one or more connecting rods. The first ends of the two handles are provided with a second locking structure, so that the first ends of the two handles can be respectively inserted into the first installation space formed by the first locking plate and the steam engine body, and into the first installation space formed by the second locking plate and the steam engine body, so that the second locking structure matches the corresponding first locking structure.

[0054] In some technical solutions, optionally, the connecting rod includes: a second connecting rod, and two ends of the second connecting rod are respectively connected to the two handles. The two handles can be connected into a whole through the second connecting rod.

[0055] In some technical schemes, optionally, a plurality of first connecting structures are arranged on one of the two handles along the length direction of the handle, and a plurality of second connecting structures are arranged on the other of the two handles along the length direction of the handle, and the connecting rod includes: a first connecting rod, and both ends of the first connecting rod are respectively connected to the two handles through any first connecting structure and any second connecting structure.

[0056] In this technical solution, the two ends of the first connecting rod are respectively connected to the two handles through any first connecting structure and any second connecting structure, so that the strength of the handles can be increased. It can be understood that since multiple connecting structures are provided on the two handles, there are multiple installation methods when installing the first connecting rod, so that the first connecting rod becomes an adjustable setting, thereby meeting the use needs of the user. Among them, when installing the handles, the first connecting rod can be held, and then the first ends of the two handles can be inserted into the first installation space for installation, which improves the installation convenience of the user, and the position of the first connecting rod can be adjusted according to different needs.

[0057] Further, the second locking structure is arranged on a side that is relatively far from the two handles. That is, the second locking structure is arranged on the outside of each handle. Of course, the second locking structure can also be arranged on the front side or the rear side of the two handles.

[0058] In some technical solutions, optionally, the lengths and structures of the two handles are the same.

[0059] In some technical solutions, optionally, the handle includes a straight rod and a curved rod.

[0060] In some technical solutions, optionally, an anti-slip structure is provided on the surface of the locking plate away from the steam engine body.

[0061] In some technical solutions, optionally, the first locking structure includes a ball head lock, and the second locking structure includes a locking hole.

[0062] In some technical solutions, optionally, a roller is provided at the bottom of the steam engine body.

[0063] In this technical solution, rollers are provided at the bottom of the steam engine body, and the steam cleaning machine can be easily moved and used by users by providing the rollers.

[0064] In some technical solutions, optionally, the roller includes a universal wheel.

[0065] In this technical solution, the roller includes a universal wheel, and the provision of the universal wheel increases the freedom of movement of the steam cleaning machine and improves the user experience.

DETAILED DESCRIPTION

[0082] In order to more clearly understand the above-mentioned purpose, features and advantages of the utility model, the utility model is further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features in the embodiments can be combined with each other without conflict.

[0083] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the protection scope of the present invention is not limited to the specific embodiments disclosed below.

[0084] Refer to the following Figures 1 to 12 The invention describes a steam cleaning machine according to some embodiments of the invention.

[0085] According to an embodiment of the first aspect of the present utility model, Figures 1 to 12 As shown, the first aspect of the utility model provides a steam cleaning machine, comprising a steam engine body 1, a locking plate 2, a handle 3 and a first elastic member 8. The locking plate 2 is arranged on the steam engine body 1, a first installation space 6 and a first opening are formed between the locking plate 2 and the steam engine body 1, and a first locking structure 22 is arranged on the locking plate 2. A second locking structure 31 is arranged on the first end of the handle 3, and the first end of the handle 3 can extend into the first installation space 6 from the first opening, and when the first end of the handle 3 is located in the first installation space 6, the first locking structure 22 can cooperate with the second locking structure 31, so that the first end of the handle 3 is limited in the first installation space 6. The first elastic member 8 is arranged on the first end of the handle 3 or in the first installation space 6, and the first elastic member 8 is in a compressed state when the first locking structure 22 cooperates with the second locking structure 31, and can generate a first force that makes the first locking structure 22 and the second locking structure 31 closely cooperate.

[0086] The steam cleaning machine provided by the utility model comprises a steam engine body 1, a locking plate 2, a handle 3 and a first elastic member 8. The handle 3 can be fixedly installed on the steam engine body 1 through the locking plate 2, so that the handle 3 can be installed when the steam cleaning machine is used, so that the steam cleaning machine can be moved by the handle 3. When the steam cleaning machine needs to be stored, the handle 3 can be removed, so that the overall volume of the steam cleaning machine can be reduced, so that it is convenient to store. At the same time, since the first elastic member 8 is arranged at the first end of the handle 3 or in the first installation space 6, when the handle 3 is installed, the deformation of the first elastic member 8 can play a role of buffering and shock absorption, improve the installation feel of the handle 3, and after the handle 3 is installed, the elastic force of the first elastic member 8 can make the first locking structure 22 and the second locking structure 31 fit more tightly, more stably and reliably, and prevent the first locking structure 22 and the second locking structure 31 from being out of fit.

[0087] Specifically, the locking plate 2 is arranged on the steam engine body 1, so that a first installation space 6 is formed between the locking plate 2 and the steam engine body 1. When the handle 3 needs to be installed, the first end of the handle 3 can be extended into the first installation space 6 through the first opening, and then an external force can be applied to the handle 3 to clamp the handle 3 and the steam engine body 1 at both ends to achieve compression of the first elastic member 8. At the same time, the handle 3 can be fixed by the cooperation of the first locking structure 22 on the locking plate 2 and the second locking structure on the handle 3. In this way, after the first locking structure 22 and the second locking structure 31 are matched, the rebound force generated by the compression of the first elastic member 8 can make one of the first locking structure 22 and the second locking structure 31 press against the other, so that the first locking structure 22 and the second locking structure 31 can be matched more tightly and stably. In addition, since the first elastic member 8 is elastic, the deformation of the first elastic member 8 can play a buffering and shock-absorbing role when the handle 3 is installed, which also helps to improve the installation feel of the handle 3. When the handle 3 needs to be removed, the first locking structure 22 and the second locking structure 31 can be disengaged first, and then the handle 3 can be removed. Fixing the handle 3 by means of the locking structure is not only convenient when installing or removing the handle 3, without the need to use tools such as a wrench, but also more reliable, thereby improving the reliability of the steam cleaning machine.

[0088] Meanwhile, the first elastic member 8 can be arranged on the first end of the handle 3 according to actual needs, or can be arranged in the first installation space 6, as long as the first elastic member 8 can be compressed and deformed by the handle 3 when the handle 3 is installed.

[0089] Among them, in the design where the first elastic member 8 is arranged in the first installation space 6, when the handle 3 needs to be installed, the first elastic member 8 can be first extended into the first installation space 6 so that the first elastic member 8 abuts against the first installation space 6, and then the handle 3 continues to be extended into the first installation space 6, and pressure is applied to the first elastic member 8 through the handle 3 until the first locking structure 22 and the second locking structure 31 can fit together.

[0090] In some embodiments, optionally, Fig. 9 As shown, the first end of the handle 3 is provided with a first mounting groove 33, and the first elastic member 8 is at least partially disposed in the first mounting groove 33. When the handle 3 and the steam engine body 1 are separated from each other, the first elastic member 8 is in a natural state.

[0091] In this embodiment, the first elastic member 8 is installed on the handle 3 , and the first installation groove 33 provides a receiving space for the first elastic member 8 .

[0092] In some embodiments, optionally, Figure 8 , Fig.10 and Fig.11 As shown, the handle 3 includes: a plug 37, which is arranged at the slot of the first mounting slot 33, and the plug 37 can slide relative to the handle 3 along the depth direction of the first mounting slot 33, one end of the first elastic member 8 abuts against the plug 37, and the other end of the first elastic member 8 abuts against the bottom wall of the first mounting slot 33; wherein, the plug 37 slides relative to the handle 3, so that the first elastic member 8 can switch between a compressed state and a natural state.

[0093] In some embodiments, optionally, a first mounting groove 33 is provided at the first end of the handle 3. The handle 3 includes: a plug 37, which is provided at the notch of the first mounting groove 33, and the plug 37 can slide relative to the handle 3 along the depth direction of the first mounting groove 33, one end of the first elastic member 8 abuts against the plug 37, and the other end of the first elastic member 8 abuts against the bottom wall of the first mounting groove 33; wherein the plug 37 slides relative to the handle 3, so that the first elastic member 8 can switch between the compressed state and the natural state.

[0094] In this embodiment, the first elastic member 8 can be installed on the handle 3 through the first installation groove 33 and the plug 37. Since the plug 37 can slide up and down relative to the handle 3, the first elastic member 8 can be compressed by the plug 37. The plug 37 can not only avoid the problem of easy loss of the first elastic member 8, but also protect the first elastic member 8 through the plug 37 to prevent the first elastic member 8 from being damaged by foreign objects.

[0095] In some embodiments, optionally, Fig.12As shown, the plug 37 includes a cover plate 370, and one end of the first elastic member 8 is in contact with the cover plate 370; a lug 372 is arranged on the cover plate 370, the lug 372 can extend into the first mounting groove 33, and one of the slideway 332 and the slider 3722 is arranged on the lug 372, and the other of the slideway 332 and the slider 3722 is arranged on the side wall of the first mounting groove 33, and the slider 3722 is slidably installed in the slideway 332; the number of the lugs 372 is two, and the two lugs 372 are arranged at a distance from each other.

[0096] In this embodiment, the cover plate 370 is used to realize the support installation of the first elastic member 8. The lug 372 can extend into the first installation groove 33, so that when the plug 37 slides relative to the handle 3, the lug 37 can be guided by the lug 372 to avoid the plug 37 from deviating when sliding. Specifically, the sliding guide of the plug 37 can be realized by the cooperation of the slideway 332 and the slider 3722 to ensure the stability of the plug 37 when sliding. There are two lugs 372, and the two lugs 372 are arranged at an interval from each other, and the first elastic member 8 is located between the two lugs 372.

[0097] In some embodiments, optionally, Fig. 9 As shown, the cover plate 370 is provided with a first positioning column 3702, the first positioning column 3702 is located between the two lugs 372, one end of the first elastic member 8 is sleeved and installed on the first positioning column 3702, and the first positioning column 3702 is provided with a first positioning hole 3704. Fig. 9 As shown, the handle 3 also includes: a second positioning column 334, which is arranged on the bottom wall of the first mounting groove 33, and a second positioning hole 336 is arranged on the second positioning column 334; a connecting member 35, one end of the connecting member 35 is installed in the second positioning hole 336, and the other end of the connecting member 35 is installed in the first positioning hole 3704; the first elastic member 8 includes a first spring 82, and the first spring 82 is sleeved and installed outside the connecting member 35.

[0098] In this embodiment, positioning posts are provided on the bottom wall of the first mounting groove 33 and the cover plate 370, and the connection between the bottom wall of the first mounting groove 33 and the plug 37 of the connecting member 35 can be achieved through the positioning posts. The first elastic member 8 includes a first spring 82. Since springs are relatively common, have good elastic effects, and are not easily damaged, the cost of the first elastic member 8 can be reduced and the service life of the first elastic member 8 can be ensured. At the same time, after the first elastic member 8 is set as the first spring 82, the first spring 82 can be sleeved and installed outside the connecting member 35, so that the deformation of the spring can be guided by the connecting member 35 to avoid the spring from being offset or stuck during the deformation process.

[0099] In some embodiments, optionally, Fig. 9 and Fig.11 As shown, a retaining rib 3724 is provided on the outer side wall of the lug 372, and the retaining rib 3724 can abut against the end of the first end of the handle 3. That is, the retaining rib 3724 can abut against the surface where the notch of the first installation groove 33 is located.

[0100] In this embodiment, the retaining rib 3724 abuts against the end of the first end of the handle 3, so that the entire plug 37 cannot completely enter the first installation groove 33, thereby preventing the spring from being over-compressed and causing the plug 37 to be stuck in the first installation groove 33.

[0101] In some embodiments, the locking plate 2 can optionally move between a first position and a second position. Figure 3 As shown, the locking plate 2 is in the first position (eg Figure 3 When the first locking structure 22 is in the position shown in the figure, the first locking structure 22 can cooperate with the second locking structure 31 to limit the first end of the handle 3 to the first installation space 6. Figure 5 As shown, the locking plate 2 is located in the second position (eg Figure 5 When the first locking structure 22 is in the position shown in the figure, the first locking structure 22 and the second locking structure 31 are disengaged.

[0102] In this embodiment, the locking plate 2 is not completely fixed on the steam engine body 1, and it can move relative to the steam engine body 1. For example, the locking plate 2 can be rotatably or slidably installed on the steam engine body 1 so that the locking plate 2 can move between the first position and the second position. When the handle 3 needs to be installed on the steam engine body 1, the locking plate 2 can be in the first position, so that the first locking structure 22 can cooperate with the second locking structure 31 to achieve the connection between the handle 3 and the steam engine body 1. When the handle 3 needs to be removed, the locking plate 2 can be moved to the second position so that the first locking structure 22 and the second locking structure 31 are released from the cooperation, so that the handle 3 can be easily removed. This setting, when the handle 3 needs to be removed, because the first locking structure 22 and the second locking structure 31 can be realized by the movement of the locking plate 2, so that the removal of the handle 3 is more labor-saving. Of course, when the handle 3 needs to be installed, the locking plate 2 can also be opened to facilitate the insertion of the handle 3, thereby achieving a labor-saving effect.

[0103] Furthermore, if Figure 3 As shown, a first guide surface is provided on the first locking structure 22. When the first end of the handle 3 extends into the first installation space 6 from the first opening, the second locking structure 31 can move along the first guide surface from one side of the first locking structure 22 to the other side of the second locking structure 31 and cooperate with the first locking structure 22.

[0104] In this embodiment, due to the provision of the first guide surface, when installing the handle 3, it is only necessary to press the handle 3 in the direction of the steam engine body 1, and the second locking structure 31 can smoothly slide to the other side of the first locking structure 22 under the guidance of the first guide surface and achieve snap fit therewith. Therefore, by providing the first guide surface, the handle 3 can be installed more smoothly and conveniently, and the user operation steps are relatively few, and it can basically be operated with one hand.

[0105] Furthermore, if Figure 3 As shown, the second locking structure 31 is provided with a second guide surface 3122, and the second guide surface 3122 can guide the second locking structure 31 to enter the first installation space 6. When the first end of the handle 3 extends into the first installation space 6 from the first opening 62, the first locking structure 22 can move along the second guide surface until the second locking structure 31 moves from one side of the first locking structure 22 to the other side of the first locking structure 22 and matches with the first locking structure 22.

[0106] In some embodiments, optionally, Fig.12 As shown, the second locking structure 31 includes: a second locking protrusion 312, which is arranged on the outer wall of the handle 3, and the end of the first locking protrusion 222 away from the handle 3 extends obliquely from the first end of the handle 3 to a direction away from the first end of the handle 3; a second card groove 314, which is surrounded by the second locking protrusion 312 and the outer wall of the handle 3; the first locking structure 22 includes a first locking protrusion 222 adapted to the second card groove 314.

[0107] In this embodiment, the handle 3 and the lock plate 2 are snap-fitted in the form of a hook, and this method can make the snap fit between the handle 3 and the lock plate 2 more stable and not easy to fall off. Further, the first lock protrusion 222 extends obliquely from the first end of the handle 3 in a direction away from the first end of the handle 3, that is, the first lock protrusion 222 is not completely perpendicular to the handle 3, and the angle between it and the handle 3 is less than 90°, that is, the edge of the first lock protrusion 222 is tilted, and this structure can further make the snap fit between the handle 3 and the lock plate 2 more stable and not easy to fall off.

[0108] Furthermore, the thickness of the first locking protrusion 222 along the extension direction of the handle 3 gradually decreases from one end close to the handle 3 to one end far away from the handle 3 , that is, the cross section of the first locking protrusion 222 is a triangle.

[0109] Of course, the handle 3 and the locking plate 2 can also be snap-fitted together by means of a slot and a protrusion.

[0110] In some embodiments, optionally, the locking plate 2 can move from the first position to the second position during the process of inserting the handle 3 into the first installation space 6 .

[0111] Furthermore, if Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, the steam cleaning machine also includes: a second elastic member 4, both ends of which are respectively connected to the locking plate 2 and the steam engine body 1, and are used to move the locking plate 2 back to the first position after the locking plate 2 moves from the first position to the second position.

[0112] In this embodiment, the elastic connection between the lock cover plate 370 and the steam engine body 1 can be achieved through the second elastic member 4, so that when the handle 3 is inserted into the first installation space 6, the lock plate 2 can move away from the steam engine body 1 to avoid the handle 3, so that the second lock structure 31 on the handle 3 can quickly pass through the first lock structure 22. After the second lock structure 31 passes through the first lock structure 22, the lock plate 2 can return to the initial position under the action of the second elastic member 4 to ensure that the second lock structure 31 and the first lock structure 22 can be matched.

[0113] In some embodiments, optionally, the locking plate 2 and the steam engine body 1 further enclose a second installation space 7, and the second elastic member 4 is located in the second installation space 7. That is, an independent installation hole is provided for the second elastic member 4, so that the second elastic member 4 and the handle 3 can be prevented from interfering with each other, making the installation of the handle 3 smoother and less prone to problems.

[0114] In some embodiments, optionally, Figure 6 and Figure 7 As shown, the steam engine body 1 includes: a second mounting groove 12, which is arranged on the side wall of the steam engine body 1, and the first side of the second mounting groove 12 is provided with an opening 122, a partition plate 14, which is arranged on the second side of the second mounting groove 12, and the second side is the other side arranged opposite to the first side; the locking plate 2 is installed at the second mounting groove 12; wherein the first mounting space 6 is surrounded by the locking plate 2, the partition plate 14, and part of the inner wall of the second mounting groove 12, and the locking plate 2, the partition plate 14, and the other part of the inner wall of the second mounting groove 12 surround the second mounting space 7, and the first mounting space 6 is located inside the second mounting space 7. The second elastic member 4 is located in the second mounting space 7.

[0115] In this embodiment, a second mounting groove 12 can be provided on the side wall of the steam engine body 1, and then a side wall of the second mounting groove 12 is opened, that is, a side wall of the second mounting groove 12 is provided with an opening 122, so that the first end of the handle 3 can be extended from the opening 122 into the second mounting groove 12, thereby realizing the installation of the handle 3. By providing the second mounting groove 12 and arranging the handle 3 in the mounting groove, the handle 3 can be limited by the side wall and the bottom wall of the mounting groove, thereby improving the stability of the installation of the handle 3. It is understandable that in the actual setting process, the direction of the opening 122 can be set according to the use requirements. For example, when the handle 3 needs to be installed above the steam engine body 1, the side wall of the second mounting groove 12 close to the upper side can be opened upward to form the opening 122, so that the first end of the handle 3 can be extended from the opening 122 formed above into the second mounting groove 12. Similarly, when the handle 3 needs to be installed at the rear of the steam engine body 1, the side wall of the second installation groove 12 close to the rear can be opened backward to form an opening 122, so that the first end of the handle 3 can be extended into the second installation groove 12 from the opening 122 formed at the rear.

[0116] Among them, the partition plate 14 is arranged in the second installation groove 12, and the first installation space 6 is formed between the partition plate 14 and the bottom wall of the second installation groove 12, and the second installation space 7 is formed between the partition plate 14 and the lock plate 2, so that the second elastic member 4 can be arranged in the second installation space 7 to form a force on the lock plate 2, so that the first lock structure 22 and the second lock structure 31 are matched. By setting the partition plate 14 to separate the first installation space 6 and the second installation space 7, interference between the second elastic member 4 and the handle 3 can be avoided, and the reliability of the setting of the second elastic member 4 is improved.

[0117] In some embodiments, optionally, Figure 5 As shown, a limiting structure 5 is further provided in the second installation space 7 , and the second elastic member 4 is provided at the limiting structure 5 .

[0118] In this embodiment, a limiting structure 5 can also be set in the second installation space 7, and the second elastic member 4 can be set at the limiting structure 5, so as to prevent the second elastic member 4 from moving, thereby improving the reliability and stability of the cooperation between the first locking structure 22 and the second locking structure 31.

[0119] In some embodiments, optionally, Figure 5 As shown, the second elastic member 4 includes a second spring 42, and the limiting structure 5 includes a limiting platform and a limiting groove 52; the second spring 42 is arranged in the limiting groove 52; or the second spring 42 is installed on the limiting platform.

[0120] In this embodiment, the second elastic member 4 includes a second spring 42, and the limiting structure 5 includes a limiting platform and a limiting groove 52, so that one end of the second spring 42 can be set in the limiting groove 52, or one end of the second spring 42 can be installed on the limiting platform, and then the other end of the second spring 42 can be abutted against the lock plate 2, so that the elastic force generated by the second spring 42 can act on the lock plate 2, thereby driving the first lock structure 22 to cooperate with the second lock structure 31. Specifically, the second spring 42 can be in a compressed state when it is set in the second installation space 7, and then when the other end of the second spring 42 is abutted against the lock plate 2, the elastic force generated by the second spring 42 can act on the lock plate 2. Since the spring has good elasticity, large deformation and low cost, it can reduce the overall production cost of the steam cleaning machine and make the device easier to assemble.

[0121] In some embodiments, the locking plate 2 is optionally connected to the steam engine body 1 in a rotational manner. This is because, compared with a sliding connection, the locking plate 2 occupies less space and has a simpler structure.

[0122] In some embodiments, optionally, Figure 7 As shown, the locking plate 2 is provided with one of the rotating shaft 24 and the shaft hole 16, and the steam engine body 1 is provided with the other of the rotating shaft 24 and the shaft hole 16.

[0123] In this embodiment, the action of the locking plate 2 relative to the steam engine body 1 can be rotation or sliding. When the locking plate 2 rotates relative to the steam engine body 1, one of the rotating shaft 24 and the shaft hole 16 can be set on the locking plate 2, and the other of the rotating shaft 24 and the shaft hole 16 can be set on the steam engine body 1, so that the locking plate 2 rotates relative to the steam engine body 1 through the cooperation of the rotating shaft 24 and the shaft hole 16. The first locking structure 22 is matched with the second locking structure 31 by rotation, which can reduce the space occupied, facilitate the setting of the locking structure, and has high stability.

[0124] In some embodiments, optionally, the locking plate 2 rotates in a direction close to and away from the steam engine body 1 .

In this way, the first locking structure 22 and the second locking structure 31 can form a good match.

[0128] In some embodiments, optionally, the locking plate 2 is slidably installed on the steam engine body 1, and the sliding of the locking plate 2 can drive the first locking structure 22 to cooperate with the second locking structure 31, or drive the first locking structure 22 to disengage from the second locking structure 31.

[0129] In this embodiment, the locking plate 2 moves relative to the steam engine body 1 by sliding. Specifically, a slide rail can be provided on the steam engine body 1, and a card block can be provided on the locking plate 2. The card block is provided in the slide rail to slide, thereby driving the first locking structure 22 to move, so as to achieve the cooperation between the first locking structure 22 and the second locking structure 31, or to achieve the disengagement between the first locking structure 22 and the second locking structure 31.

[0130] In some embodiments, optionally, Figures 1 to 12 As shown, there are two locking plates 2, and two second locking structures 31 are respectively arranged on two opposite sides of the steam engine body 1; there are two handles 3, and the two handles 3 are arranged opposite to each other, and each handle 3 is correspondingly provided with a second locking structure 31 and a first elastic member 8; the two handles 3 are connected by a connecting rod.

There are also two handles 3, and the two handles 3 are connected by one or more connecting rods. The first ends of the two handles 3 are both provided with a second locking structure 31, so that the first ends of the two handles 3 can be respectively inserted into the first installation space 6 formed by one locking plate 2 and the steam engine body 1, and the first installation space 6 formed by the other locking plate 2 and the steam engine body 1, so that the second locking structure 31 matches the corresponding first locking structure 22.

[0132] In some embodiments, optionally, Figure 7 As shown, the connecting rod includes: a second connecting rod 94, and both ends of the second connecting rod 94 are respectively connected to the two handles 3. The two handles 3 can be connected into a whole through the second connecting rod 94.

[0133] In some embodiments, optionally, Figure 1As shown, one of the two handles 3 is provided with a plurality of first connection structures along the length direction of the handle 3, and the other of the two handles 3 is provided with a plurality of second connection structures along the length direction of the handle 3, and the connecting rod includes: a first connecting rod 92, and both ends of the first connecting rod 92 are respectively connected to the two handles 3 through any first connection structure and any second connection structure.

[0134] In this embodiment, the two ends of the first connecting rod 92 are respectively connected to the two handles 3 through any first connecting structure and any second connecting structure, so that the strength of the handles 3 can be increased. It can be understood that since multiple connecting structures are set on the two handles 3, there are multiple installation methods when installing the first connecting rod 92, so that the first connecting rod 92 becomes an adjustable setting, thereby meeting the user's use needs. Among them, when installing the handles 3, the first connecting rod 92 can be held, and then the first ends of the two handles 3 are inserted into the first installation space 6 to achieve installation, which improves the user's installation convenience, and the position of the first connecting rod 92 can be adjusted according to different needs.
