[0034] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0035] The disclosure below provides many different embodiments or examples for realizing different structures of the utility model. In order to simplify the disclosure of the utility model, the components and settings of specific examples are described below. Of course, they are merely examples, and the purpose is not to limit the utility model. In addition, the utility model can repeat reference numbers and / or letters in different examples. This repetition is for the purpose of simplification and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the utility model provides various specific examples of processes and materials, but those of ordinary skill in the art can be aware of the applicability of other processes and / or the use of other materials.

[0036] Hereinafter, with reference to the accompanying drawings, a hair washing device 100 according to an embodiment of the present invention will be described.

[0037] like Figure 1-Figure 2 and Figure 5 As shown, the hair washing device 100 includes a frame 1, a water tank 2 and a fixing assembly 3, wherein the water tank 2 is separable from the frame 1; the fixing assembly 3 includes a first locking structure 31, and the first locking structure 31 is switchable between a first state and a second state.

[0038] In the first state, the first locking structure 31 is suitable for locking the water tank 2 and the frame 1 to fix the water tank 2 on the frame 1, which is conducive to ensuring the stable setting of the water tank 2 and preventing the water tank 2 from moving, tilting or rolling during the process of moving the hair washing device 100, which may cause the liquid in the water tank 2 to spill out, which is conducive to increasing the safety of the hair washing device 100 and reducing the workload of cleaning personnel (such as cleaning). In the second state, the first locking structure 31 is suitable for releasing the lock on the water tank 2 and the frame 1 to unlock the lock between the water tank 2 and the frame 1, which is convenient for moving or carrying the water tank 2. The operator can separate the water tank 2 from the frame 1 so that the operator has a suitable operating space, which is convenient for the operator to clean or replace the water tank 2, or it is convenient for the operator to operate the water tank 2 to increase the liquid in the water tank 2 (such as clean water) or clean the liquid in the water tank 2 (such as waste water). Therefore, by switching the state of the first locking structure 31 (the first state or the second state), it is convenient to lock the water tank 2 and the frame 1 or release the lock between the water tank 2 and the frame 1, which facilitates the disassembly and assembly of the water tank 2 and can improve the work efficiency of handling the water tank 2.

[0039] Among them, the fixing component 3 also includes a limiting structure 32, and the limiting structure 32 can be switched between a third state and a fourth state. When the first locking structure 31 is in the first state, if the limiting structure 32 is switched to the third state, the limiting structure 32 cooperates with the first locking structure 31 to lock the first locking structure 31. When the first locking structure 31 is in the first state and the limiting structure 32 is in the third state, the limiting structure 32 can keep the first locking structure 31 in the first state to ensure that the first locking structure 31 realizes reliable and stable locking between the water tank 2 and the frame 1. If the limiting structure 32 is switched to the fourth state, the limiting structure 32 disengages from the first locking structure 31 to release the first locking structure 31. When the limiting structure 32 is in the fourth state, the limiting structure 32 can release the lock of the first locking structure 31, and the first locking structure 31 can be switched from the first state to the second state, so that the first locking structure 31 can release the lock on the water tank 2 and the frame 1.

[0040] Therefore, the limiting structure 32 can improve the stability of the first locking structure 31 when it is in the first state, which is beneficial to improving the reliability and stability of the first locking structure 31 locking the water tank 2 and the frame 1, so that the shampooing device 100 can adapt to more complex movement conditions and keep the water tank 2 stable on the frame 1.

[0041] Exemplarily, the shampooing device 100 is used for washing and cleaning patients in hospitals or nursing homes as an example for explanation. The shampooing device 100 includes two water tanks 2 and two fixed components 3. One of the water tanks 2 is used to store clean water so as to provide clean water for washing the head of patients (mobile or bedridden patients, etc.), and the other water tank 2 is used to store sewage so as to collect sewage generated by shampooing. Each fixed component 3 cooperates with the corresponding water tank 2. By arranging the two water tanks 2 on the frame 1 and switching the corresponding first locking structure 31 to the first state, the two water tanks 2 are fixed on the frame 1. At the same time, the limiting structure 32 is switched to the third state, and the limiting structure 32 and the first locking structure 31 are locked. The fixed structure 31 cooperates to lock the first locking structure 31, so that the first locking structure 31 remains in the first state, to ensure that the locking of the first locking structure 31 is reliable and stable, so that the operator can move the shampooing device 100, to ensure the stability of the water tank 2 arranged on the frame 1 during the movement, to avoid the water tank 2 rolling or overturning, etc., which causes the clean water or sewage to spill out and increase the cleaning and disinfection process, which is beneficial to reduce the risk of hospital infection, and to ensure that the water tank 2 is reliably fixed during the cleaning process, which can prevent the patient or the operator from overturning the water tank 2, which is beneficial to reduce the workload of the operator and avoid danger to the patient, etc., and can improve the safety of the shampooing device 100. Secondly, by switching the limiting structure 32 to the fourth state to release the lock of the first locking structure 31, the first locking structure 31 can be switched to the second state to release the lock between the corresponding water tank 2 and the frame 1, so as to facilitate the transportation of the water tank 2, so as to facilitate the operator to add clean water and clean sewage, or clean and disinfect the water tank 2, thereby facilitating the disassembly and assembly of the water tank 2 and improving work efficiency and safety. Of course, the water tank 2 can also be one, three or more.

[0042] According to the hair washing device 100 of the embodiment of the utility model, the first locking structure 31 is provided to be switchable between the first state and the second state, so as to facilitate the locking or unlocking of the water tank 2 and the frame 1, which is conducive to ensuring the stable setting of the water tank 2, facilitating the disassembly and assembly of the water tank 2, and improving the working efficiency of handling the water tank 2. The limiting structure 32 can improve the stability of the first locking structure 31 in the first state, which is conducive to improving the reliability and stability of the first locking structure 31 locking the water tank 2 and the frame 1, so that the hair washing device 100 can adapt to more complex movement conditions and keep the water tank 2 stable on the frame 1.

[0043] In some embodiments, in combination Figure 3-Figure 5 The first locking structure 31 includes a fixed member 311, a movable member 312 and a first locking member 313. The fixed member 311 is fixed to the frame 1. The movable member 312 is separable from the frame 1 and is suitable for being spaced apart from the fixed member 311 to define a clamping space for clamping the water tank 2, so that the fixed member 311 and the movable member 312 can stabilize the water tank 2 to ensure the stability of the setting of the water tank 2. It can be seen that when the movable member 312 is arranged on the frame 1, the movable member 312 is spaced apart from the fixed member 311, so that a clamping space is formed between the movable member 312 and the fixed member 311, and after the movable member 312 is separated from the frame 1, the first locking structure 31 cannot clamp the water tank 2.

[0044] It can be seen that the first locking structure 31 achieves the fixation of the water tank 2 and the frame 1 by clamping the water tank 2, so as to securely lock the water tank 2 and the frame 1, and at the same time, it is conducive to improving the force of the fixing member 311 and the movable member 312. Optionally, the movable member 312 is suitable for being arranged with a spacing from the fixing member 311 in the horizontal direction, and the bottom wall of the clamping space is defined by the frame 1, and the frame 1 supports and bears the water tank 2, thereby reducing the force of the fixing member 311 and the movable member 312.

[0045] The first locking member 313 is movably arranged on the movable member 312 and the first locking member 313 can be switched between a locking position and an unlocking position. In the locking position, the first locking member 313 cooperates with the frame 1 to lock the position of the movable member 312, so that the first locking structure 31 is in the first state, and the first locking member 313 locks the relative position between the movable member 312 and the frame 1, so that the fixed member 311 and the movable member 312 cooperate with each other to fix the water storage tank 2 on the frame 1; in the unlocking position, the first locking member 313 is disengaged from the frame 1 to release the movable member 312, so that the first locking structure 31 is in the second state, and the first locking member 313 unlocks the lock between the movable member 312 and the frame 1, so that the fixed member 311 and the movable member 312 can release the fixation of the water storage tank 2, so that the water storage tank 2 can be separated from the frame 1, thereby facilitating the disassembly and assembly of the water storage tank 2.

[0046] The limiting structure 32 is used to lock or release the first locking member 313. When the first locking member 313 is in the locked position, the limiting structure 32 switches to the third state and cooperates with the first locking member 313 to lock the first locking member 313, so that the first locking member 313 remains in the locked position to ensure that the locking of the first locking member 313 is reliable and stable. When the first locking member 313 is in the locked position, the limiting structure 32 switches to the fourth state and disengages from the first locking member 313 to release the lock on the first locking member 313, so that the first locking member 313 can be switched to the unlocked position (for example, the first locking member 313 is moved to the unlocked position), so that the first locking member 313 releases the lock between the movable member 312 and the frame 1, that is, the lock of the fixed member 311 and the movable member 312 on the water storage tank 2 can be released.

[0047] Optionally, the movable part 312 and the water tank 2 may be an integral part or separate parts.

[0048] In some embodiments, in combination Figure 2-Figure 4 A matching groove 311a is formed on the surface of one side of the fixing member 311 that contacts the water tank 2. The matching groove 311a can accommodate part of the water tank 2, and the groove wall of the matching groove 311a fits with part of the surface of the water tank 2, so that the matching groove 311a has a certain positioning effect on the water tank 2 in at least two directions to ensure that the water tank 2 is accurately positioned on the frame 1; it can be seen that when the movable member 312 is provided on the frame 1, the matching groove 311a is formed on the side of the fixing member 311 facing the movable member 312, the fixing member 311 and the movable member 312 are respectively matched with the water tank 2, and the groove wall of the matching groove 311a cooperates with part of the surface of the water tank 2, so that the water tank 2 can be stably arranged in the clamping space, ensuring that the water tank 2 is reliably fixed.

[0049] For example, combined with Figure 3-Figure 5The water tank 2 has a cover and a body, the cover is used to close the body, and a handle 2a is provided on the body, which allows the operator to better operate and move the water tank 2; the water tank 2 is formed into a hollow cylindrical structure (such as a bucket), and the fixed part 311 and the movable part 312 are arranged on the frame 1 at intervals along the front and rear directions, and a clamping space is defined between the fixed part 311 and the movable part 312. A matching groove 311a is formed on the side of the fixed part 311 facing the movable part 312, and the matching groove 311a is an arc groove. A first locking part 313 is provided on the surface of the movable part 312 facing away from the fixed part 311. The process of fixing the water tank 2 to the frame 1 is as follows: the outer peripheral wall of the water tank 2 is first fitted with the groove wall of the matching groove 311a to preliminarily locate the position of the water tank 2 on the frame 1, then the movable member 312 is arranged on the side of the water tank 2 away from the fixed member 311, and the first locking member 313 locks the movable member 312 to clamp the water tank 2 in the clamping space. Of course, the movable member 312 can also be arranged with a left and right spacing from the fixed member 311.

[0050] In some embodiments, in combination Figure 5-Figure 6 The first locking member 313 has a first plug-in portion 313b, and the frame 1 is formed with a second plug-in portion 1a. The first plug-in portion 313b is suitable for plugging and matching with the second plug-in portion 1a. When the first plug-in portion 313b is plugged with the second plug-in portion 1a, the first locking member 313 is in a locked position to lock the movable member 312 and the frame 1, so as to fix the movable member 312 on the frame 1. When the first plug-in portion 313b is separated from the second plug-in portion 1a, the first locking member 313 is in an unlocked position, and the movable member 312 can be separated from the frame 1. As a result, the switching efficiency of the first locking member 313 between the locked position and the unlocked position is improved, thereby improving the switching efficiency of the first locking structure 31 between the first state and the second state.

[0051] For example, in Figure 5-Figure 6 In the example, the first locking member 313 has a first plug-in portion 313b, which forms a columnar structure. A second plug-in portion 1a is formed on the frame 1, and the second plug-in portion 1a is formed as a slot or a socket. When the first locking member 313 is switched to the locked position, the first plug-in portion 313b is plugged into and matched with the second plug-in portion 1a to fix the movable member 312 on the frame 1. When the first locking member 313 is switched to the unlocked position, the first plug-in portion 313b is disengaged from the second plug-in portion 1a to release the fixation between the movable member 312 and the frame 1.

[0052] In some embodiments, in combination Figure 6The hair washing device 100 further includes an elastic member 41, which is used to apply an elastic force to the first locking member 313 to move toward the unlocking position. Therefore, when the limiting structure 32 switches from the third state to the fourth state, the limiting structure 32 disengages from the first locking member 313, that is, the locking of the first locking member 313 is released, and the elastic force of the elastic member 41 can make the first locking member 313 switch from the locking position to the unlocking position by itself, so that the elastic member 41 can facilitate the unlocking process of the first locking member 313, which is conducive to improving work efficiency.

[0053] It can be understood that when the first locking member 313 is not subjected to other forces (for example, the limiting structure 32 is in the fourth state, etc.), the elastic member 41 will apply an elastic force to the first locking member 313 to move toward the unlocked position, so that the first locking member 313 remains in the unlocked position when it is not subjected to other forces, thereby avoiding the first locking member 313 (for example, the first locking member 313 is in the locked position) from interfering with components such as the frame 1 when the movable member 312 is moved, etc., thereby affecting the setting of the movable member 312.

[0054] In some embodiments, in combination Figure 5-Figure 6 The limiting structure 32 includes a limiting member 321, which is movable relative to the first locking member 313 to achieve the switching of the limiting structure 32 between the third state and the fourth state; the moving direction of the limiting member 321 (for example Figure 5 The left-right direction in the figure) and the movement direction of the first locking member 313 from the locking position to the unlocking position (for example Figure 6 The upper and lower directions in the figure intersect, so that when the limiting member 321 abuts against the first locking member 313, the limiting structure 32 switches to the third state, and when the limiting member 321 separates from the first locking member 313, the limiting structure 32 switches to the fourth state. Thus, when the first locking member 313 switches to the locked position and the limiting structure 32 switches to the third state, the limiting member 321 abuts against the first locking member 313 to limit the movement of the first locking member 313, and when the first locking member 313 switches to the unlocked position and the limiting structure 32 switches to the fourth state, the limiting member 321 separates from the first locking member 313 to release the lock on the first locking member 313, so that the limiting member 321 can move along the moving direction to lock or release the first locking member 313, and the limiting structure 32 has a simple structure and is convenient to switch between the first state and the second state.

[0055] Optionally, the moving direction of the limiter 321 is perpendicular to the moving direction of the first locking member 313 from the locked position toward the unlocked position, which can effectively reduce the tendency of the limiter 321 to move under the force applied by the first locking member 313, and is conducive to improving the locking reliability of the limiter 321 on the first locking member 313. Of course, the moving direction of the fiber member 321 can also be at any angle other than 90° to the moving direction of the first locking member 313 from the locked position toward the unlocked position.

[0056] In some embodiments, in combination Figure 5 , the first locking member 313 and the movable member 312 are aligned in the vertical direction (eg Figure 6 The limiter 321 and the movable member 312 slide together in the horizontal direction (for example Figure 5 Thus, the first locking member 313 moves relative to the movable member 312 in the vertical direction to switch between the locking position and the unlocking position, so as to achieve locking or releasing between the movable member 312 and the frame 1, and the limiting member 321 moves relative to the movable member 312 in the horizontal direction to lock or release the first locking member 313 when the first locking member 313 is in the locking position, thereby facilitating the disassembly and assembly of the water storage tank 2.

[0057] Optionally, the limiting member 321 is movably disposed on the movable member 312, so as to simplify the structure of the frame 1. Of course, in other examples, the limiting member 321 can also be movably disposed on the frame 1.

[0058] For example, in Figure 5 and Figure 6In the example of the embodiment, the first locking member 313 and the limiting member 321 are both arranged on the movable member 312, the first locking member 313 and the movable member 312 slide and cooperate in the up and down directions, the locking position of the first locking member 313 is located at the lower side of the unlocking position, the limiting member 321 and the movable member 312 slide and cooperate in the left and right directions, the first locking member 313 has a first plug-in portion 313b, and the frame 1 has a second plug-in portion 1a. When the first locking member 313 moves downward to the locking position, the first plug-in portion 313b and the second plug-in portion 1a are plug-in-coordinated to complete the locking between the movable member 312 and the frame 1, and the limiting member 321 can be When the movable part 312 moves a certain distance toward the left side, the limiting member 321 contacts the first locking member 313 to limit the first locking member 313 from moving upward and leaving the locked position; when the limiting member 321 moves a certain distance toward the right side relative to the movable part 312, the limiting member 321 separates from the first locking member 313. At this time, the limiting member 321 releases the restriction on the first locking member 313, and the first locking member 313 is located on the left side of the limiting member 321. The first locking member 313 can move upward to the unlocking position, and the first plug-in portion 313b disengages from the second plug-in portion 1a to release the lock between the movable part 312 and the frame 1.

[0059] Of course, the hair washing device 100 also includes an elastic member 41, which can apply an elastic force to the first locking member 313 to move toward the unlocking position. When the limiting member 321 releases the restriction on the first locking member 313, the first locking member 313 automatically moves to the unlocking position and completes the unlocking under the action of the elastic member 41. When the first locking member 313 needs to be switched to the locked position, the first locking member 313 can be pushed to move to the locked position by pressing downward.

[0060] Optionally, the movable member 312 is formed with a first sliding groove 312a, and the first locking member 313 includes a first sliding portion 313a, and the first sliding portion 313a is slidably matched with the groove wall of the first sliding groove 312a in the vertical direction, thereby, the first sliding portion 313a moves in the first sliding groove 312a in the vertical direction so that the first locking member 313 switches between the locking position and the unlocking position, so as to achieve the locking or release between the movable member 312 and the frame 1. Exemplarily, in the horizontal direction, the slot width of the first sliding groove 312a is smaller than the slot bottom width of the first sliding groove 312a, for example, the first sliding groove 312a is formed as a T-shaped groove or a dovetail groove, etc., and the cross-sectional shape and size of the first sliding portion 313a are consistent with the cross-sectional shape and size of the first sliding groove 312a, so as to ensure reliable sliding fit between the first sliding portion 313a and the first sliding groove 312a.

[0061] Optionally, the movable member 312 is further formed with a second sliding groove, and the limiting member 321 has a second sliding portion, and the second sliding portion slides and cooperates with the groove wall of the second sliding groove in a horizontal direction. Figure 5 When the first locking piece 313 switches to the locked position, the operator can push the limit piece 321 to move horizontally to the left, so that part of the bottom surface of the limit piece 321 contacts part of the top surface of the first locking piece 313, so that the position of the first locking piece 313 is restricted and cannot move upward. The limit piece 321 locks the first locking piece 313. When the limit piece 321 is pushed to move horizontally to the right, the limit piece 321 separates from the first locking piece 313. At this time, the limit piece 321 is located on the right side of the first locking piece 313, and the limit piece 321 releases the lock on the first locking piece 313.

[0062] It can be understood that the movement direction of the first locking member 321 relative to the movable member 312 is not limited to movement, and the first locking member 321 can also rotate relative to the movable member 312; illustratively, the upper end of the first locking member 321 is rotationally connected to the movable member 312, and in the locked position, the first locking member 321 is vertically arranged, and in the unlocked position, the first locking member 321 is horizontally arranged, then the movement direction of the first locking member 321 from the locked position toward the unlocked position can be understood as the movement direction of the lower end of the first locking member 321, that is, the horizontal direction, and the movement direction of the limit member 321 can be at a non-zero angle with the horizontal direction.

[0063] In some embodiments, in combination Figure 5 The hair washing device 100 also includes a second locking piece 51, which is movable relative to the limiting piece 321 and has a preset position. The second locking piece 51 is configured so that when the limiting structure 32 is switched to the third state, the second locking piece 51 moves to the preset position under the action of its own gravity to limit the limiting structure 32 from leaving the third state, so that the limiting structure 32 can remain in the third state, so as to ensure that the limiting structure 32 limits the movement of the first locking piece 313 and remains in the locked position, so as to avoid the limiting structure 32 and the first locking piece 313 being easily separated due to the movement or vibration of the hair washing device 100, so as to cause the first locking piece 313 to release the lock between the movable piece 312 and the frame 1, thereby facilitating further improving the stability and reliability of the locked state when the first locking piece 313 is in the locked position, so as to improve the setting stability of the water storage tank 2. Secondly, when the limiting structure 32 switches to the third state, the second locking member 51 can move to the preset position under the action of its own gravity to limit the limiting structure 32 from leaving the third state. After the limiting structure 32 switches to the third state, it can trigger the second locking member 51 to move toward the preset position, so that the second locking member 51 can use gravity to achieve a certain degree of automatic ability, which can reduce a certain amount of operation.

[0064] Among them, the triggering method of triggering the second locking member 51 to move toward the preset position after the limiting structure 32 switches to the third state includes but is not limited to the following: after the limiting structure 32 switches to the third state, a certain movement space is freed up for the second locking member 51 to move toward the preset position, so that the second locking member 51 spontaneously moves toward the preset position under the action of its own gravity.

[0065] It can be seen that in some embodiments, if the limiting structure 32 includes a limiting member 321, the limiting member 321 is movable relative to the first locking member 313, and the limiting member 321 can have a first position and a second position. In the first position, the limiting member 321 is stopped against the first locking member 313, and the limiting structure 32 switches to the third state. In the second position, the limiting member 321 is separated from the first locking member 313, and the limiting structure 32 switches to the fourth state; then, when the second locking member 51 is in the preset position, the space occupied by the second locking member 51 is the preset space. When the limiting member 321 moves to the first position, the limiting member 321 does not occupy the preset space, and the second locking member 51 can move to the preset position under the action of its own gravity. When the limiting member 321 moves to the second position, the limiting member 321 occupies at least part of the preset space, and the second locking member 51 cannot move to the preset position. It can be seen that the second locking member 51 can move to the preset position, that is, the position locking of the limiting member 321 can be implemented.

[0066] In some embodiments, in combination Figure 5 The second locking member 51 and the movable member 312 slide together in the vertical direction. The limiting structure 32 includes a limiting member 321. The limiting member 321 and the movable member 312 slide together in the horizontal direction. The two ends of the limiting member 321 in its moving direction are respectively a first end and a second end.

[0067] In the third state, the first end abuts against the first locking member 313, and the second end abuts against the second locking member 51 in the moving direction of the limiting member 321. It can be seen that the limiting member 321 limits the movement of the first locking member 313 so that the first locking member 313 remains in the locked position, and at the same time, the second locking member 51 limits the movement of the limiting member 321 so that the limiting member 321 remains in a state of limiting the movement of the first locking member 313.

[0068] In the fourth state, the first end is separated from the first locking piece 313, and the upper surface of the second end is abutted against the second locking piece 51 in the vertical direction. It can be seen that the second locking piece 51 releases the lock on the limiting piece 321, so that the limiting piece 321 can be separated from the first locking piece 313, so that the first locking piece 313 can move to the unlocked position. At the same time, the limiting piece 321 occupies a part of the space so that the second locking piece 51 cannot move to the preset position.

[0069] For example, combined with Figure 5, the limit member 321 moves in the left and right directions, and the first end is located on the left side of the second end. When the first locking member 313 is in the locked position, the lower surface of the first end abuts against the upper surface of the first locking member 313, and the right side surface of the second end abuts against the second locking member 51; when the first locking member 313 is in the unlocked position, the first end is separated from the first locking member 313, the first end is located on the left side of the first locking member 313, and the upper surface of the second end abuts against the lower surface of the second locking member 51. Optionally, the movable member 312 is also formed with a second sliding groove and a third sliding groove, the limit member 321 has a second sliding portion, and the second sliding portion slides with the groove wall of the second sliding groove in a horizontal direction, and the second locking member 51 has a third sliding portion, and the third sliding portion slides with the groove wall of the third sliding groove in a vertical direction. For example, in combination with Figure 5 When the limiting structure 32 switches to the third state, the second locking member 51 moves downward to a preset position relative to the third sliding groove under the action of its own gravity, and the side of the second locking member 51 contacts the side of the limiting member 321, so that the limiting member 321 cannot move, that is, the second locking member 51 restricts the limiting member 321 from leaving the locked position.

[0070] In some embodiments, in combination Figure 5 and Figure 6 The hair washing device 100 further includes an unlocking structure 4, which is used to drive the first locking structure 31 to switch to the second state, so that after the limiting structure 32 releases the first locking structure 31, the first locking structure 31 can release the lock between the water storage tank 2 and the frame 1 (for example, release the lock between the movable part 312 and the frame 1) under the action of the unlocking structure 4. Therefore, the unlocking process of the first locking structure 31 can be simplified through the unlocking structure 4, reducing the difficulty of operation, which is conducive to improving work efficiency.

[0071] In some embodiments, in combination Figure 6 The unlocking structure 4 includes an elastic member 41, and the elastic member 41 is used to apply an elastic force to the first locking structure 31 to switch to the second state. Therefore, when the limiting structure 32 switches from the third state to the fourth state, the limiting structure 32 is disengaged from the first locking structure 31, that is, the limiting structure 32 releases the lock on the first locking structure 31, so that the first locking structure 31 can automatically switch from the first state to the second state under the action of the elastic member 41, so that the elastic member 41 can facilitate the unlocking process of the first locking structure 31, which is conducive to improving work efficiency.

[0072] In some embodiments, in combination Figure 5The hair washing device 100 further includes a second locking structure 5, which is movable relative to the frame 1 and has a preset state. When the limiting structure 32 is in the third state, if the second locking structure 5 is in the preset state, the second locking structure 5 locks the limiting structure 32. If the second locking structure 5 leaves the preset state, the second locking structure 5 releases the limiting structure 32. Therefore, when the limiting structure 32 is in the third state and the second locking structure 5 is in the preset state, the second locking structure 5 can keep the limiting structure 32 in the third state, which is conducive to improving the reliability and stability of the locking of the first locking structure 31, that is, the setting stability of the water storage tank 2 can be improved.

[0073] In some embodiments, in combination Figure 5 The second locking structure 5 includes a second locking member 51, which moves in the vertical direction, and the second locking member 51 is configured such that when the limiting structure 32 switches to the third state, the second locking member 51 moves to a preset position under the action of its own gravity to switch the second locking structure 5 to the preset state. Thus, when the limiting structure 32 switches to the third state, the second locking member 51 moves to the preset position under the action of its own gravity to keep locking the limiting structure 32, so that the second locking member 51 can use the action of gravity to achieve a certain degree of automaticity, and can reduce a certain amount of operation.

[0074] In some embodiments, in combination Figure 1 and Figure 2 , at least part of the frame 1 is constructed as a cabinet structure 11, which is conducive to improving the structural reliability and bearing capacity of the frame 1; a receiving chamber 11a is defined in the cabinet structure 11, and an opening 11b is formed on one side of the receiving chamber 11a. The water storage tank 2 is suitable for being received in the receiving chamber 11a through the opening 11b, so that the water storage tank 2 can be taken out from the opening 11b or stored in the receiving chamber 11a. A movable cabinet door 11c is provided at the opening 11b to open and close the opening 11b. Thus, the water storage tank 2 is arranged in the receiving chamber 11a of the cabinet structure 11. When the cabinet door 11c closes the opening 11b, the cabinet structure 11 has a certain sealing storage function. Even if part of the liquid (such as clean water or sewage) in the water storage tank 2 is spilled, the receiving chamber 11a can receive part of the spilled liquid, which can prevent the spilled liquid from falling on the ground and increasing the workload of cleaning and disinfection.

[0075] In some embodiments, in combination Figure 1 and Figure 2, at least one water storage tank 2 is a clean water tank 21 for storing clean water, the shampooing device 100 also includes a water outlet 6 and a pumping part 7, the pumping part 7 is connected to the water outlet 6 to pump water in the clean water tank 21 to the water outlet 6, the water outlet 6 is connected to the pumping part 7 through a retractable hose 10a, and the distance between the water outlet 6 and the pumping part 7 is variable, which is convenient for operators (such as nurses, etc.) to operate the water outlet 6 to perform a cleaning process; and / or, at least one water storage tank 2 is a sewage tank 22 for storing sewage, the cabinet structure 11 is formed with a sewage trough 22a, the top side of the sewage trough 22a is open and the bottom side of the sewage trough 22a is formed with a drain port 22b connected to the sewage tank 22, the sewage trough 22a can provide a suitable cleaning space so as to collect sewage in a larger range and store the collected sewage in the sewage tank 22 through the drain port 22b.

For example, A and / or B can represent: A exists alone, A and B exist at the same time, and B exists alone. In addition, the character " / " in this article generally indicates that the associated objects before and after are in an "or" relationship.

[0077] Therefore, the hair washing device 100 includes a clean water tank 21 and a dirty water tank 22. The pumping member 7 is connected to the water outlet member 6 to pump the water in the clean water tank 21 to the water outlet member 6.

The upper surface of the first cabinet part 111 is higher than the upper surface of the second cabinet part 112. The water outlet part 6 is arranged above the first cabinet part 111, and the sewage tank 22a is arranged on the top of the second cabinet part 112, so that the water outlet part 6 is located at a higher position, which is convenient for taking or placing the water outlet part 6, and can reduce the water sprayed by the water outlet part 6 from being sprinkled on the upper surface of the first cabinet part 111, which is conducive to ensuring the cleanliness of the first cabinet part 111.

[0079] In some embodiments, in combination Figure 1A pull-out storage box 8 is provided on the upper portion of the first cabinet portion 111 , so that relevant hair washing appliances and the like can be stored in the storage box 8 .

[0080] Among them, the upper surface of the first cabinet part 111 is higher than the upper surface of the second cabinet part 112, so the first cabinet part 111 has more space than the second cabinet part 112 to facilitate the installation of the storage box 8, thereby making the structural design of the cabinet structure 11 more reasonable and more ingenious.

[0081] In some embodiments, in combination Figure 1 When at least one water storage tank 2 is a clean water tank 21 for storing clean water, the shampooing device 100 further includes a massage member 6a, which is arranged on the water outlet member 6.

The bottom wall of the sewage tank 22a is provided with a headrest portion 22d protruding from the bottom wall. Thus, the neck of the user (for example, a patient) can fit with the neck pillow portion 22c (for example, the arc-shaped surface), and the head of the user is placed on the headrest portion 22d, which is convenient for the operator to wash the head of the user and can make the user feel more comfortable.

[0082] Optionally, the massage part 6a is a flexible part (such as a silicone brush head); for example, the water outlet part 6 is constructed as a shower head, and the shower head is provided with a silicone brush head, so that the water outlet part 6 can flush the foam more finely during the cleaning process, and the silicone brush head has the effect of massaging the scalp; a flexible pad (such as a silicone cushion) is provided on the neck pillow 22c, which can further improve the comfort of the user's neck.
