Abstract
Description
Technical Field
[0001] This utility model relates to the field of connection technology for cleaning household appliances, and in particular to a connection structure for cleaning household appliances and a cleaning household appliance. Background Technology
[0002] To meet the high-efficiency demands of modern home space utilization, cleaning appliances often employ modular designs, disassembling the entire appliance into multiple independent components. These components are then connected via a robust connection structure to achieve stable assembly and flexible combination. Similarly, at the level of intelligent operation, the stable power transmission between cleaning appliances and the power supply system relies on a reliable connection structure. This connection structure is not only crucial for modular assembly but also a core hub ensuring stable power transmission and automated operation. Its performance directly impacts the user experience and safety of the cleaning appliances, playing an indispensable and decisive role in product design and functionality.
[0003] Currently, some household cleaning appliances have connection structures where a first limiting protrusion is provided on the first connector, and a second limiting protrusion is provided on the second connector. The first limiting protrusion is located at the lower end of the second limiting protrusion, and the first limiting protrusion abuts against the second limiting protrusion to connect the first and second connectors. When the first limiting protrusion is lifted away from the second limiting protrusion, the first and second connectors separate. However, while the operator uses one hand to lift the first limiting protrusion away from the second limiting protrusion, the other hand needs to hold the second connector to prevent it from suddenly falling off and causing damage. When one of the operator's hands is operating other machines, only one hand can be used to separate the first and second connectors, and the second connector may suddenly fall off and cause damage.
[0004] Therefore, there is an urgent need for a connection structure for cleaning household appliances that can solve the problem of separation between two connected parts when connected with one hand, and prevent damage to the connected parts or the operator caused by the sudden detachment of one of the two connected parts. Utility Model Content
[0005] The purpose of this utility model is to provide a connection structure for cleaning household appliances and a cleaning household appliance, which can solve the problem of separation of two connecting parts when connected by one hand, and prevent one of the two connecting parts from suddenly falling off and causing damage to the connecting parts or the operator.
[0006] Based on the above concept, the technical solution adopted by this utility model is as follows:
[0007] A connection structure for a cleaning household appliance includes:
[0008] The first component to be connected has a first receiving groove on its side;
[0009] The second component to be connected is plugged into and unplugged into the first component to be connected, and the second component to be connected protrudes outward at the location corresponding to the first receiving groove to form a protrusion.
[0010] A connecting assembly is disposed within the first receiving groove. The connecting assembly includes a locking member and a snap-fit member. The locking member is connected to the snap-fit member and is rotatably connected to the first member to be connected.
[0011] When the locking member is rotated to the point where the latching member can engage with the upper end of the protrusion, the connecting assembly is in the unlocked state.
[0012] When the locking member is rotated to the point where the snap-fit member can abut against the lower end of the protrusion, the first member to be connected is connected to the second member to be connected, and the connecting assembly is in a locked state.
[0013] As an optional connection structure for the cleaning household appliance, a second receiving groove is provided on the side of the locking member facing the first member to be connected. The connection assembly also includes a first elastic member, which is connected to the snap-fit member from top to bottom. Both the first elastic member and the snap-fit member are accommodated in the second receiving groove.
[0014] As an optional connection structure for this type of household cleaning appliance, the first elastic element is a first spring.
[0015] As an optional connection structure for this cleaning household appliance, the snap-fit component extends horizontally toward the center of the first component to be connected. The end of the snap-fit component near the protrusion along its extension direction is bent downward to form a first snap-fit hook. The upper end of the protrusion is bent upward along the extension direction of the snap-fit component near the snap-fit component to form a second snap-fit hook. When the connection assembly is in the unlocked state, the first snap-fit hook and the second snap-fit hook engage with each other to achieve snap-fit between the second component to be connected and the connection assembly.
[0016] As an optional connection structure for this cleaning household appliance, the lower end of the locking member is bent upward to form a limiting part. When the connection component is in the locked state, the limiting part abuts against the lower end of the protrusion.
[0017] As an optional connection structure for the cleaning household appliance, the connection assembly further includes a limiting member disposed on the side of the locking member facing the first member to be connected. The limiting member extends vertically, and the first elastic member is disposed within the area enclosed by the locking member and the limiting member.
[0018] As an optional connection structure for the cleaning household appliance, the connection assembly further includes a second elastic member, one end of which is connected to the limiting member along its elastic direction, and the other end of which is connected to the first member to be connected.
[0019] As an optional connection structure for the cleaning household appliance, a third receiving groove is provided at the connection point between the first component to be connected and the second elastic component, along the elastic direction of the second elastic component, and at least part of the second elastic component is received in the third receiving groove.
[0020] As an optional connection structure for this cleaning household appliance, the first component to be connected has a vertically oriented insertion groove, which is located inside the first component to be connected and extends circumferentially along the first component to be connected. The second component to be connected is inserted into the insertion groove.
[0021] The cleaning appliance includes a first cleaning appliance body, a second cleaning appliance body, and a connection structure for the cleaning appliance. The first cleaning appliance body is connected to the first component to be connected, and the second cleaning appliance body is connected to the second component to be connected.
[0022] The beneficial effects of this utility model are as follows:
[0023] This utility model proposes a connection structure for cleaning household appliances. A first receiving groove is formed on the side of a first component to be connected. A second component to be connected is plugged into and pulled into the first component. The second component protrudes outwards from the corresponding location in the first receiving groove, forming a protrusion. A connecting assembly is disposed within the first receiving groove. The connecting assembly includes a locking member and a snap-fit member. The locking member is rotatably connected to the first component to be connected and is connected to a limiting member. When the locking member rotates to the point where the snap-fit member can snap into the upper end of the protrusion, the connecting assembly is in an unlocked state. When the locking member rotates to the point where the snap-fit member abuts against the lower end of the protrusion, the first and second components to be connected are connected, and the connecting assembly is in a locked state. Through this design, when the upper end of the locking member is pressed to rotate it to the unlocked state, the first and second components to be connected remain connected. This feature significantly optimizes the operation process, eliminating the need for the operator to simultaneously press the locking member and hold the second component to prevent it from suddenly falling off and being damaged. The lock can be opened with one hand, freeing up the other hand and greatly improving ease of use and safety, while effectively reducing the risk of damage to parts due to accidental detachment.

[0037] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.
[0038] This embodiment provides a connection structure for cleaning household appliances, such as... Figures 1-3 As shown, in this embodiment, the connection structure of the cleaning household appliance includes a first connector 1, a second connector 2, and a connection assembly 3. The first connector 1 has a first receiving groove 11 on its side. The second connector 2 is pluggably connected to the first connector 1. The second connector 2 protrudes outward at the corresponding position of the first receiving groove 11 to form a protrusion 21. The connection assembly 3 is disposed in the first receiving groove 11. The connection assembly 3 includes a locking member 31 and a snap-fit member 32. The locking member 31 is connected to a limiting member 34 and is rotatably connected to the first connector 1. When the locking member 31 is rotated until the snap-fit member 32 can snap into the upper end of the protrusion 21, the connection assembly 3 is in an unlocked state. When the locking member 31 is rotated until the snap-fit member 32 can abut against the lower end of the protrusion 21, the first connector 1 and the second connector 2 are connected, and the connection assembly 3 is in a locked state. With the above design, when the upper end of the locking member 31 is pressed and rotated to the unlocked state, the first connecting member 1 and the second connecting member 2 can still remain connected. This feature significantly optimizes the operation process, eliminating the need for the operator to hold the second connecting member 2 tightly with their hand to prevent it from suddenly falling off and being damaged while pressing the locking member 31. The unlocking action can be completed with a single hand, completely freeing up the other hand, greatly improving operational convenience and safety, and effectively reducing the risk of component damage due to accidental detachment.
[0039] Specifically, such as Figures 1-2 As shown, in this embodiment, the locking member 31 has a second receiving groove 311 on the side facing the first member to be connected 1. The connecting assembly 3 also includes a first elastic member 33, which is connected to the snap-fit member 32 from top to bottom. Both the first elastic member 33 and the snap-fit member 32 are accommodated in the second receiving groove 311. Since the first elastic member 33 and the snap-fit member 32 are connected and both are accommodated in the second receiving groove 311, the snap-fit member 32 can move elastically to a certain extent. When the snap-fit member 32 contacts the protrusion 21, the first elastic member 33 can be compressed, thereby better adapting to the shape and position changes of the protrusion 21 and ensuring the reliability of the snap-fit. When the connection structure of a cleaning household appliance is subjected to external impact or vibration, the first elastic member 33 can play a buffering role, reducing the rigid collision between the snap-fit member 32 and the protrusion 21, and reducing the risk of component damage caused by impact and vibration.
[0040] Optionally, such as Figures 1-3 As shown, in this embodiment, the first elastic element 33 is a first spring, which has good elastic deformation and restoring ability. When the locking member 31 is pressed to make the latching member 32 slide relative to the upper end of the protrusion 21, the first spring is compressed and produces elastic deformation. When the latching member 32 is latched to the upper end of the protrusion 21, the first spring can return to its original shape, driving the latching member 32 back to its initial position. During the operation of the connecting component 3, whether locking or unlocking, a certain impact force will be generated when the latching member 32 contacts the protrusion 21. The first spring can absorb these impact forces and buffer them through its own elastic deformation, reducing the rigid collision between the latching member 32 and the protrusion 21. In other embodiments, the first elastic element 33 can also be a first rubber block or a first silicone block, as long as it can provide elastic force for the latching member 32 to slide relative to the locking member 31 in the vertical direction.
[0041] Preferably, such as Figures 1-3As shown, in this embodiment, the latching member 32 extends horizontally towards the center of the first component to be connected 1. The latching member 32 bends downwards at one end near the protrusion 21 along its extension direction to form a first latching hook 321. The upper end of the protrusion 21 bends upwards at one end near the latching member 32 along its extension direction to form a second latching hook 211. When the connecting assembly 3 is in the unlocked state, the first latching hook 321 and the second latching hook 211 engage, thus latching the second component to be connected 2 to the connecting assembly 3. This ensures that the first component to be connected 1 and the second component to be connected 2 remain connected in the unlocked state, preventing the second component to be connected 2 from suddenly falling off. This gives the overall structure a certain degree of stability even in the unlocked state, preventing accidental detachment. The above design further improves operational convenience. The operator does not need to use their hand to grip the second component to be connected 2 to prevent it from falling; they only need to operate the locking member 31. The unlocking action can be completed with a single hand, freeing up the other hand and improving operational efficiency. In other embodiments, the snap-fit component 32 and the first component to be connected 1 can be a snap-fit structure or a wedge snap-fit structure, as long as it can ensure that the first component to be connected 1 and the second component to be connected 2 remain connected after unlocking.
[0042] Preferably, such as Figures 1-2 As shown, in this embodiment, the lower end of the locking member 31 is bent upward to form a limiting part 312. When the connecting component 3 is in the locked state, the limiting part 312 abuts against the lower end of the protrusion 21 to lock it. When the limiting part 312 abuts against the lower end of the protrusion 21, it can effectively restrict the movement of the second component 2 relative to the first component 1, ensuring that the two will not easily loosen or separate in the connected state, thereby ensuring the stability of the connection structure of the cleaning household appliance during normal use, so that the entire structure can work reliably. This mechanical abutment method can provide the operator with clear locking feedback. When the limiting part 312 abuts against the lower end of the protrusion 21, the operator can intuitively judge by touch that the connecting component 3 is in the locked state, thereby confirming that the first component 1 and the second component 2 are firmly connected, avoiding misoperation caused by uncertainty about the connection state. In other embodiments, the connection between the locking member 31 and the first member to be connected 1 can also be a slot and hook structure or a bolt and nut structure, as long as it can ensure a stable connection between the first member to be connected 1 and the second member to be connected 2 when locked.
[0043] Specifically, such as Figures 1-2As shown, in this embodiment, the connecting component 3 further includes a limiting member 34. The limiting member 34 is disposed on the side of the locking member 31 facing the first component to be connected 1. The limiting member 34 extends vertically, and the first elastic member 33 is disposed in the area enclosed by the locking member 31 and the limiting member 34. The limiting member 34 extends vertically and encloses the area with the locking member 31, confining the first elastic member 33 within this area. This ensures that the first elastic member 33 will not move arbitrarily during operation, guaranteeing that it is always in the predetermined working position and exerts its due elastic effect. The positioning function of the limiting member 34 on the first elastic member 33 ensures the stability of the entire connecting component 3 during operation, preventing the connecting component 3 from failing or malfunctioning due to the displacement of the first elastic member 33, thereby improving the overall stability of the connection structure between the first component to be connected 1 and the second component to be connected 2, which are household cleaning appliances.
[0044] Optionally, in this embodiment, the limiting member 34 and the locking member 31 are connected by a fastener 35. In other embodiments, the limiting member 34 and the locking member 31 can be connected by welding or riveting, etc., as long as it can fix the limiting member 34 to the locking member 31. Optionally, in this embodiment, the fastener 35 is a bolt. In other embodiments, the fastener 35 can also be a pin structure or a key structure, etc.
[0045] Specifically, such as Figures 1-3 As shown, in this embodiment, the connecting component 3 further includes a second elastic member 36. One end of the second elastic member 36 along its elastic direction is connected to the limiting member 34, and the other end of the second elastic member 36 along its elastic direction is connected to the first member to be connected 1. When the second member to be connected 2 is disengaged from the first member to be connected 1, the locking member 31 can automatically return to the locked state. The function of automatically returning to the locked state allows the operator to reset the locking member 31 without additional operation after disassembling the second member to be connected 2, simplifying the operation process, saving time and effort, and improving work efficiency. This convenience is especially significant when the second member to be connected 2 needs to be frequently disassembled and installed.
[0046] Optionally, such as Figures 1-3 As shown, in this embodiment, the second elastic element 36 is a second spring. The second spring has a simple structure and stable performance, and its elastic properties can remain stable for a relatively long time, ensuring the reliability and durability of the automatic reset function of the connecting component 3. A spring is a common and low-cost elastic element. Compared with other complex elastic devices, using a second spring as the second elastic element 36 can effectively reduce the manufacturing cost of the connecting component 3 and improve the product's cost-effectiveness. In other embodiments, the second elastic element 36 can also be a second rubber block or a second silicone block, as long as it can provide elastic force for the locking element 31 to automatically return to the locked state.
[0047] Preferably, such as Figures 1-2 As shown, in this embodiment, a third receiving groove 12 is provided at the connection point between the first component to be connected 1 and the second elastic member 36, along the elastic force direction of the second elastic member 36. At least a portion of the second elastic member 36 is accommodated within the third receiving groove 12. The third receiving groove 12 provides a clear installation position for the second elastic member 36, ensuring that the second elastic member 36 can be accurately placed on the first component to be connected 1 during installation, ensuring that its elastic force direction is consistent with the design requirements, and guaranteeing that the second elastic member 36 can function normally. Accommodating at least a portion of the second elastic member 36 within the third receiving groove 12 can restrict the second elastic member 36 from moving or swinging in other directions during operation. During the extension and retraction of the second elastic member 36, the sidewall of the third receiving groove 12 can constrain it, preventing the second elastic member 36 from shifting or twisting, and ensuring that its elastic deformation is along the predetermined elastic force direction.
[0048] Preferably, such as Figures 1-2 As shown, in this embodiment, the first component to be connected 1 has a vertically oriented insertion groove 13. The insertion groove 13 is located inside the first component to be connected 1 and extends circumferentially. The second component to be connected 2 is inserted into the insertion groove 13. The insertion groove 13 allows the second component to be connected 2 to be inserted into the first component to be connected 1 along the extending direction of the insertion groove 13. The insertion groove 13 provides clear guidance and positioning for the insertion of the second component to be connected 2, enabling operators to insert the second component to be connected 2 into the appropriate position more accurately and quickly during installation, improving installation efficiency and accuracy, and reducing installation difficulty. The first component to be connected 1, the second component to be connected 2, and the connecting component 3 work together to further improve the connection and locking functions between the first component to be connected 1 and the second component to be connected 2. When the locking component 31 is in the unlocked or locked state, the insertion groove 13 can ensure that the second component to be connected 2 exists stably within a certain range, working in conjunction with the locking structure to improve the overall structural safety and operational convenience. In other embodiments, the first component to be connected 1 and the second component to be connected 2 can also be screwed or magnetically connected, as long as it can provide a more stable and accurate connection between the first component to be connected 1 and the second component to be connected 2.
[0049] Preferably, such as Figures 1-5As shown, in this embodiment, a pressing part 313 is recessed into the upper half of the side of the locking member 31 facing away from the first member to be connected 1. The pressing part 313 provides a clear pressing position for the operator, allowing them to easily press the locking member 31, thereby rotating it and switching the connecting component 3 between the unlocked and locked states. Specifically, when the pressing part 313 is pressed, the locking member 31 rotates to the unlocked state, and the engaging member 32 engages with the upper end of the protrusion 21. The recessed design of the pressing part 313 better conforms to the shape of the finger, increasing the contact area and friction between the finger and the locking member 31 during pressing, making the pressing action more comfortable, stable, and precise, thus improving the operator's experience. With the clear pressing part 313, the operator can find the pressing position more quickly and accurately without having to fumble or search for a suitable pressing point, greatly improving operational convenience, especially in situations with limited operating space or insufficient light.
[0050] For ease of understanding, combined with Figures 1-5 This section explains the working process of the connection structure of cleaning household appliances. Specifically, when the first component to be connected 1 and the second component to be connected 2 are to be separated, the connecting assembly 3 is in a locked state, that is, the latching member 32 is in contact with the lower end of the protrusion 21. When the pressing part 313 is pressed, the connecting assembly 3 begins to rotate, and the latching member 32 separates from the lower end of the protrusion 21, so that the connecting assembly 3 is in an unlocked state. Since the first latching hook 321 and the second latching hook 211 are engaged with each other, the second component to be connected 2 remains connected to the first component to be connected 1 and will not fall off the first component to be connected 1. Then the operator pulls out the second component to be connected 2, realizing the separation of the first component to be connected 1 and the second component to be connected 2. When the second component to be connected 2 is pulled out, the locking member 31 automatically rotates to the default position due to the action of the second elastic member 36. When the second component to be connected 2 is reinserted into the first component to be connected 1, the connecting assembly 3 will automatically lock the second component to be connected 2, that is, return to the locked state, realizing the connection between the first component to be connected 1 and the second component to be connected 2.
[0051] This embodiment also discloses a cleaning household appliance, which includes a first cleaning household appliance body, a second cleaning household appliance body, and a connection structure for the cleaning household appliance. The first cleaning household appliance body is connected to a first connecting part 1, and the second cleaning household appliance body is connected to a second connecting part 2. When the upper end of the locking part 31 is pressed and rotated to the unlocked state, the first cleaning household appliance body and the second cleaning household appliance body can still maintain the connection. There is no need to press the locking part 31 while holding the second cleaning household appliance body tightly to prevent it from suddenly falling off and being damaged. The unlocking action can be completed by holding it with one hand, completely freeing up the other hand and facilitating the operation of the operator. This is especially advantageous for some scenarios that require one-handed operation or have limited operating space.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here.
