DETAILED DESCRIPTION

[0040] The embodiments of the present application will now be described in further detail by way of example with reference to the accompanying drawings. The following examples are provided to illustrate the present application and should not be construed to limit the scope of the present application.

In addition, the terms "first", "second", "third" are only for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0042] In the description of the embodiments of the present application, it should be noted that unless otherwise explicitly specified and limited, the terms "communication" and "connection" should be understood broadly, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through intermediate medium. For those skilled in the art, the specific meaning of the above terms in the embodiments of the present application can be understood according to the specific circumstances.

[0043] In the related art, when a user uses a liquid suction device, the user needs to unscrew a dispenser first, so that the dispenser is separated from a bottle body. Then, the user uses the dispenser to suck cosmetic in a container, and the whole operation process is relatively cumbersome.

[0044] Based on the above situation, the present application provides an automatic liquid suction device 10. Please refer to Figures 1 to 11 The automatic liquid suction device 10 comprises a containing device 11 and a dispenser 12, and the dispenser 12 is detachably connected with the containing device 11. The containing device 11 has a containing cavity 11a. The containing cavity 11a is used for placing cosmetic. The dispenser 12 comprises an inner shell 121, a pumping assembly 122 and an outer shell 123. The inner shell 121 is detachably connected with the containing device 11. The inner shell 121 has a liquid suction channel 121a. The pumping assembly 122 comprises a pressing member 1221 and a supporting member 1222. At least part of the supporting member 1222 is sleeved outside the pressing member 1221. At least part of the pressing member 1221 can slide in the liquid suction channel 121a. The pressing member 1221 is in sealing fit with the inner wall of the liquid suction channel 121a. The outer shell 123 is sleeved outside the pumping assembly 122 and the inner shell 121, and can drive the supporting member 1222 to move along the height direction of the automatic liquid suction device 10 by driving the outer shell 123, and the supporting member 1222 drives the pressing member 1221 to slide in the liquid suction channel 121a, and forms negative pressure or positive pressure in the liquid suction channel 121a.

[0045] It should be noted that the axes of the automatic liquid suction device 10, the containing device 11 and the dispenser 12 in the present application substantially coincide or completely coincide.

[0046] Exemplarily, the automatic liquid suction device 10 and the containing device 11 are in cylindrical shape.

[0047] It should be noted that the automatic liquid suction device 10, the container 11 and the dispenser 12 in the present application are all in the same height direction.

[0048] The detachable connection between the dispenser 12 and the container 11 can be a threaded connection, a clamping connection or other forms.

[0049] Exemplarily, the container 11 has an opening which is in communication with the accommodation cavity 11a, the container 11 is at least in the part provided with the opening in a cylindrical shape, and is provided with an external thread, and the dispenser 12 is provided with an internal thread, and the dispenser 12 and the container 11 are connected through the cooperation of the external thread and the internal thread, so that the user can separate or combine the dispenser 12 and the container 11 by rotating the dispenser 12.

[0050] It should be noted that, along the height direction of the automatic liquid suction device 10, from the top to the bottom of the automatic liquid suction device 10, the separation of the dispenser 12 and the container 11 is usually achieved by counterclockwise rotation of the dispenser 12, and the combination of the dispenser 12 and the container 11 is achieved by clockwise rotation of the dispenser 12.

[0051] The embodiments of the present application are described by taking the separation of the dispenser 12 and the container 11 by counterclockwise rotation of the dispenser 12 and the combination of the dispenser 12 and the container 11 by clockwise rotation of the dispenser 12 as an example.

[0052] It should be noted that the cosmetic placed in the accommodation cavity 11a can be in a liquid state, a solid state or a solid-liquid mixed state, or in a colloidal state, a powder state and the like, which is not limited herein.

[0053] The embodiments of the present application are described by taking the cosmetic in the accommodation cavity 11a as an example.

[0054] Specifically, one end of the liquid suction channel 121a is in sealing cooperation with the pressing piece 1221, and the other end extends into the accommodation cavity 11a through the opening of the container 11 and is in liquid communication with the cosmetic in the accommodation cavity 11a. Among them, the liquid suction channel 121a between the sealing cooperation of the liquid suction channel 121a and the pressing piece 1221 and the liquid communication of the liquid suction channel 121a and the cosmetic is a liquid suction section.

[0055] It can be understood that when the pressing member 1221 moves away from the accommodating cavity 11, the volume of the liquid suction section increases, the pressure decreases, and a negative pressure is formed. Due to the pressure difference between the liquid suction section and the outside, the end of the liquid suction channel 121a in communication with the cosmetic liquid can automatically suck in the cosmetic liquid. When the pressing member 1221 moves towards the accommodating cavity 11a, the volume of the liquid suction section decreases, the pressure increases, and a positive pressure is formed. Due to the pressure difference between the liquid suction section and the outside, the gas or liquid in the liquid suction channel 121a can be automatically discharged from the end in communication with the cosmetic liquid.

[0056] Exemplarily, the inner shell 121 includes a dropper and a sub-shell. The sub-shell is provided with an inner hole for sealingly cooperating with the pressing member 1221. One end of the dropper extends into the inner hole and forms a sealing connection with the inner hole. The lumen of the dropper and the inner hole jointly define the liquid suction channel 121a. At least a part of the pressing member 1221 can slide in the inner hole and form a negative pressure or a positive pressure in the liquid suction channel 121a.

[0057] Exemplarily, the automatic liquid suction device 10 further includes a liquid scraping member 13. The liquid scraping member 13 is arranged at the opening of the accommodating cavity 11 and tightly cooperates with the dropper. Thus, when the dropper is taken out of the accommodating cavity 11a, the liquid scraping member 13 can scrape off the cosmetic attached to the outer wall of the dropper.

[0058] It should be noted that the outer shell 123 is sleeved outside the pumping assembly 122 and the inner shell 121. The outer shell 123 is fixedly connected with the inner shell 121, constitutes the entire external shell of the dispenser 12, and defines a containing space. The pumping assembly 122 is arranged in the containing space.

[0059] At least a part of the supporting member 1222 is sleeved outside the pressing member 1221. Meanwhile, the outer shell 123 is sleeved outside the pumping assembly 122 and the inner shell 121. In this way, the outer shell 123, the supporting member 1222 and the pressing member 1221 are arranged from outside to inside in sequence. When the outer shell 123 is driven, the outer shell 123 can directly drive the supporting member 1222 inside. The supporting member 1222 can also directly drive the pressing member 1221 inside the supporting member 1222. The transmission structure is simplified, the occupied space of the transmission structure is reduced, and the volume of the automatic liquid suction device 10 is reduced.

[0060] It should be noted that the supporting member 1222 can be driven to move along the height direction of the automatic liquid suction device 10 by driving the outer shell 123. This means that the outer shell 123 and the supporting member 1222 have a structure similar to a threaded transmission or a threaded transmission. The rotational motion of the outer shell 123 can be converted into the linear motion of the supporting member 1222 along the height direction of the automatic liquid suction device 10. Thus, the pressing member 1221 is also driven to move along the height direction of the automatic liquid suction device 10, and the sliding of the pressing member 1221 in the liquid suction channel 121a is realized.

[0061] Exemplarily, the shell 123 is capable of rotating relative to the container 11 around the central axis of the automatic liquid sucker 10.

[0062] Exemplarily, the material of the automatic liquid sucker 10 is plastic, for example, the material of the automatic liquid sucker 10 includes polypropylene (PP).

[0063] The automatic liquid sucker 10 provided by the embodiment of the present application has the following advantages. On the one hand, at least part of the supporting member 1222 is sleeved outside the pressing member 1221, and the shell 123 is sleeved outside the pumping assembly 122 and the inner shell 121, so that the shell 123, the supporting member 1222 and the pressing member 1221 are sequentially arranged from outside to inside, so that when the shell 123 is driven, the shell 123 can directly drive the supporting member 1222 inside, and the supporting member 1222 can directly drive the pressing member 1221 inside the supporting member 1222, thereby simplifying the transmission structure and reducing the occupied space of the transmission structure. On the other hand, when the shell 123 is rotated, the rotation of the shell 123 is converted into the linear motion of the supporting member 1222 along the height direction of the automatic liquid sucker 10, thereby driving the pressing member 1221 to move along the height direction of the automatic liquid sucker 10, realizing the sliding of the pressing member 1221 in the liquid suction channel 121a, thereby changing the volume of the liquid suction section of the liquid suction channel 121a, enabling the liquid suction section to form negative pressure or positive pressure, enabling the liquid suction channel 121a to automatically suck or discharge the cosmetic, and enabling the user to automatically suck the cosmetic during the process of rotating the shell 123 to open the automatic liquid sucker 10, thereby improving the convenience of the operation of taking the cosmetic and improving the experience of the user.

[0064] In some embodiments, referring to Figures 1 to 11 , the pumping assembly 122 has a first state and a second state. The shell 123 can drive the pressing member 1221 to rotate synchronously to switch the pumping assembly 122 between the first state and the second state. In the first state, the pressing member 1221 and the supporting member 1222 are limited in the height direction of the automatic liquid sucker 10 to enable the supporting member 1222 to drive the pressing member 1221 to move in the height direction of the automatic liquid sucker 10. In the second state, the pressing member 1221 can move relative to the supporting member 1222 along the height direction of the automatic liquid sucker 10, and the supporting member 1222 limits the pressing member 1221 in the rotation direction. By driving the shell 123, the pressing member 1221 and the supporting member 1222 can be rotated to separate the dispenser 12 from the container 11.

[0065] It should be noted that the first state is a state when the automatic liquid suction device 10 is not used normally, at this time, the distributor 12 is connected with the containing device 11, and at the same time, the pressing piece 1221 cannot move in the height direction relative to the support piece 1222 due to the mutual limiting between the pressing piece 1221 and the support piece 1222 in the height direction of the automatic liquid suction device 10, which improves the situation that the pressing piece 1221 is frequently moved in the height direction due to the accidental touch of the pressing piece 1221, and improves the compactness of the structure between the pressing piece 1221 and the support piece 1222.

[0066] Exemplarily, in the first state, the top of the pressing piece 1221 is substantially parallel to the top of the shell 123, so as to improve the appearance of the automatic liquid suction device 10 when not in use, and the integrity of the automatic liquid suction device 10 is better.

[0067] The shell 123 can drive the pressing piece 1221 to rotate synchronously, which means that the shell 123 and the pressing piece 1221 have a bidirectional limiting structure in the rotation direction, so that the rotation of the shell 123 can drive the pressing piece 1221 to rotate synchronously in both the first state and the second state.

[0068] Exemplarily, the inner wall of the shell 123 is provided with a guide groove 123b extending in the height direction, and the outer wall of the pressing piece 1221 is provided with a protruding part 1221b, the guide groove 123b and the protruding part 1221b are slidingly matched in the height direction, and the guide groove 123b of the shell 123 limits the protruding part 1221b on both sides in the rotation direction, so as to drive the pressing piece 1221 to rotate synchronously.

[0069] In addition, since the support piece 1222 limits the pressing piece 1221 in the rotation direction, and at the same time, the shell 123 can drive the pressing piece 1221 to rotate synchronously, that is, the shell 123 and the pressing piece 1221 have a bidirectional limiting structure in the rotation direction, so that in the second state, the shell 123 is locked relative to the support piece 1222 in the rotation direction through the pressing piece 1221, at this time, if the shell 123 continues to rotate in the same direction, the shell 123 will drive the pressing piece 1221 and the support piece 1222 to rotate together, and the support piece 1222 and the shell 123 will not rotate relative to each other, so that in the second state, the pressing piece 1221 is in the maximum stroke position in the height direction.

[0070] The shell 123 drives the pressing piece 1221 and the support piece 1222 to rotate together, which can make the distributor 12 rotate relative to the containing device 11, so as to realize the separation of the distributor 12 and the containing device 11.

[0071] It should be noted that the rotating direction of the shell 123 is consistent when switching from the first state to the second state, that is, the user only needs to rotate the shell 123 in the same rotating direction to switch the automatic liquid suction device 10 from the first state to the second state, and then separate the dispenser 12 from the container 11. When the user removes the dispenser 12, the dispenser 12 has completed the automatic liquid suction, and the user only needs to press the pressing piece 1221 to discharge the cosmetic in the liquid suction channel 121a. In this way, the user only needs to operate by one rotation and one pressing to use the cosmetic stored in the containing cavity 11a, which improves the convenience of user operation.

[0072] In the second state, the pressing piece 1221 can move relative to the support piece 1222 in the height direction of the automatic liquid suction device 10, that is, the limiting structure between the pressing piece 1221 and the support piece 1222 in the height direction of the automatic liquid suction device 10 in the first state no longer constitutes a limit, and the user can press the pressing piece 1221 at any time to discharge the cosmetic in the liquid suction channel 121a.

[0073] It should be noted that the shell 123 can drive the pressing piece 1221 to rotate synchronously, and at the same time, the shell 123 drives the pressing piece 1221 to move in the height direction of the automatic liquid suction device 10 through the support piece 1222, that is, the pressing piece 1221 moves in the height direction of the automatic liquid suction device 10 while rotating synchronously with the shell 123; in the first state, the movement of the pressing piece 1221 is spiral ascent or spiral descent.

[0074] In some embodiments, referring to Figures 3 to 7 and Figure 9 , the pumping assembly 122 further comprises an elastic piece 1223. The elastic piece 1223 is arranged between the pressing piece 1221 and the support piece 1222. Under the action of an external force, the pressing piece 1221 can move in the height direction of the automatic liquid suction device 10 towards the container 11 and compress the elastic piece 1223 to form a positive pressure in the liquid suction channel 121a. In a natural state, the elastic piece 1223 can restore the elastic deformation and drive the pressing piece 1221 to reset to form a negative pressure in the liquid suction channel 121a.

[0075] Illustratively, the elastic piece 1223 is made of an elastic material, for example, the elastic piece 1223 is a silica gel piece or a rubber piece, so that the elastic piece 1223 can be elastically deformed and store elastic potential energy under the action of an external force.

[0076] Illustratively, the elastic piece 1223 is a spring.

[0077] The elastic member 1223 is arranged between the pressing member 1221 and the support member 1222, and can be connected with the pressing member 1221 and the support member 1222 respectively, or connected with the support member 1222 and arranged at a certain distance from the pressing member 1221 in the height direction, and the pressing member 1221 contacts the elastic member 1223 after moving a certain stroke towards the support member 1222, and compresses the elastic member 1223.

[0078] Exemplarily, in the first state, both ends of the elastic member 1223 in the height direction abut against the pressing member 1221 and the support member 1222 respectively, the elastic member 1223 is in a state of slight elastic deformation, and the elastic member 1223 can lift the pressing member 1221 towards the top in the height direction, thereby improving the situation that the pressing member 1221 is prone to loosen after assembly due to assembly error, and reducing the assembly gap between each part of the pumping assembly 122.

[0079] Under the action of an external force, the pressing member 1221 subjected to the external force can move towards the containing vessel 11 in the height direction of the automatic liquid suction device 10, i.e. towards the support member 1222, and compress the elastic member 1223, the elastic member 1223 stores elastic potential energy, the volume of the liquid suction section of the liquid suction channel 121a decreases, and the pressure increases, so that a positive pressure is formed in the liquid suction channel 121a. It can be understood that at this time, the pumping assembly 122 is in the second state, and due to the pressure difference between the liquid suction section and the outside, the positive pressure can make the gas or liquid in the liquid suction channel 121a discharge from the liquid suction channel 121a.

[0080] In a natural state, the elastic potential energy of the elastic member 1223 drives the pressing member 1221 to reset due to the removal of the external force applied to the pressing member 1221, and the pressing member 1221 moves away from the support member 1222, while the elastic member 1223 recovers from elastic deformation. At this time, the pumping assembly 122 is in the second state, the volume of the liquid suction section of the liquid suction channel 121a increases, the pressure decreases, and a negative pressure is formed in the liquid suction channel 121a. Due to the pressure difference between the liquid suction section and the outside, the end of the liquid suction channel 121a connected with the cosmetic liquid can suck in gas or liquid.

[0081] In some embodiments, please refer to Figures 1 to 11 In the first state, the shell 123 can drive the support member 1222 to simultaneously move the pressing member 1221 and the elastic member 1223 in the height direction of the automatic liquid suction device 10.

[0082] It should be noted that in the related art, when the pressing member 1221 moves along the height direction to automatically suck liquid, one end of the elastic member 1223 is usually fixed, and the other end rises with the pressing member 1221. Considering that the elastic member 1223 needs to lift the pressing member 1221 to reset the pressing member 1221 after automatically sucking liquid, the elastic member 1223 usually needs to be in a compressed state, i.e., pre-compressed, before automatically sucking liquid, and the compression amount is large.

[0083] In this embodiment, the support member 1222 supports the elastic member 1223 along the height direction to drive the elastic member 1223 to move along the height direction of the automatic liquid sucker 10. The support member 1222 drives the pressing member 1221 to move along the height direction through the limiting structure between the pressing member 1221 and the support member 1222 along the height direction. In this way, the shell 123 can drive the entire pumping assembly 122, i.e., the pressing member 1221, the elastic member 1223, and the support member 1222, to move at least along the height direction of the automatic liquid sucker 10 synchronously by driving the support member 1222, so that when the shell 123 drives the pressing member 1221 to move along the height direction to automatically suck liquid, the elastic member 1223 moves along the height direction together with the pressing member 1221, which reduces the pre-compression amount of the elastic member 1223 in the first state and prolongs the service life of the elastic member 1223.

[0084] In some embodiments, referring to Figures 3 to 7 and Figure 9 , one of the outer wall of the pressing member 1221 and the inner wall of the support member 1222 is provided with a limiting groove 1222a, and the other is provided with a limiting protrusion 1221a. In the first state, the limiting groove 1222a and the limiting protrusion 1221a are in sliding fit to enable the support member 1222 to drive the pressing member 1221 to move along the height direction of the automatic liquid sucker 10, and the pressing member 1221 can rotate relative to the support member 1222.

[0085] One of the outer wall of the pressing member 1221 and the inner wall of the support member 1222 is provided with a limiting groove 1222a, and the other is provided with a limiting protrusion 1221a. The limiting groove 1222a and the limiting protrusion 1221a can be in sliding fit in the first state, so that the sleeve structure of the support member 1222 and the pressing member 1221 is more reliable.

[0086] In the first state, the limiting groove 1222a and the limiting protrusion 1221a are in sliding fit, so that the support 1222 can drive the pressing member 1221 to move along the height direction of the automatic liquid suction device 10, and the pressing member 1221 can rotate relative to the support 1222, that is, the limiting groove 1222a and the limiting protrusion 1221a are in sliding fit along the rotating direction of the pressing member 1221, and the rotation of the shell 123 also drives the support 1222 to move along the height direction, and the limiting groove 1222a and the limiting protrusion 1221a limit along the height direction, so that the support 1222 can drive the pressing member 1221 to move along the height direction until the pumping assembly 122 enters the second state.

[0087] In some embodiments, referring to Figures 3 to 7 and Figure 9 , the limiting protrusion 1221a is arranged on the outer wall of the pressing member 1221. The limiting groove 1222a is arranged on the inner wall of the support 1222. The support 1222 is further provided with a stop surface 1222b. In the second state, the limiting protrusion 1221a is separated from the limiting groove 1222a, and the stop surface 1222b limits the limiting protrusion 1221a in the rotating direction, so that the pressing member 1221 can drive the support 1222 to rotate.

[0088] In this embodiment, the stop surface 1222b is used to abut the limiting protrusion 1221a on the pressing member 1221 after the limiting protrusion 1221a is separated from the limiting groove 1222a, so as to limit in the rotating direction.

[0089] Exemplarily, the side wall of the support 1222 is formed with a gap penetrating through the side wall of the support 1222, the gap is in communication with the limiting groove 1222a, and the side wall of the end of the gap away from the limiting groove 1222a forms a limiting surface. In the second state, after the limiting protrusion 1221a is separated from the limiting groove 1222a, the limiting protrusion 1221a enters the gap and contacts the limiting surface, so as to realize the rotation of the shell 123, the pressing member 1221 and the support 1222 together.

[0090] In some embodiments, referring to Figures 9 to 11The inner wall of the outer shell 123 is provided with a first transmission part 123a. The outer wall of the support 1222 is provided with a second transmission part 1222c. At least part of the support 1222 is sleeved on the outer shell 121. The inner wall of the support 1222 and the outer wall of the inner shell 121 are formed with a guide groove 1222d and a guide protrusion 121b respectively. The guide groove 1222d extends along the height direction of the automatic liquid suction device 10 and is in sliding fit with the guide protrusion 121b. The outer shell 123 can drive the support 1222 through the cooperation of the first transmission part 123a and the second transmission part 1222c. The inner shell 121 limits the support 1222 in the rotation direction through the cooperation of the guide groove 1222d and the guide protrusion 121b, so that the outer shell 123 drives the support 1222 to move along the height direction of the automatic liquid suction device 10.

[0091] Exemplarily, the first transmission part 123a is an internal thread, the second transmission part 1222c is an external thread, and the outer shell 123 and the support 1222 are in threaded transmission. When the outer shell 123 rotates, the support 1222 has a tendency of spiral movement under the action of the thread slope force.

[0092] Since the inner shell 121 limits the support 1222 in the rotation direction through the cooperation of the guide groove 1222d and the guide protrusion 121b, the tendency of spiral movement of the support 1222 is changed into movement along the height direction of the automatic liquid suction device 10.

[0093] Meanwhile, the guide groove 1222d extends along the height direction of the automatic liquid suction device 10 and is in sliding fit with the guide protrusion 121b. The guide groove 1222d can guide the support 1222 to move along the height direction, so that the support 1222 moves along the height direction of the automatic liquid suction device 10 more smoothly.

[0094] In some embodiments, referring to Figure 8 and Figure 10 The inner shell 121 is provided with a clamping part 121c, and the container 11 is provided with a clamping protrusion 11b. In the first state, the clamping part 121c cooperates with the clamping protrusion 11b, and the container 11 limits the inner shell 121. In the second state, the outer shell 123 can drive the support 1222 to rotate through the pressing piece 1221, and the support 1222 can drive the inner shell 121 to rotate, so that the clamping part 121c of the inner shell 121 is separated from the clamping protrusion 11b.

[0095] It should be noted that the clamping part 121c can also be arranged on the container 11, and the clamping protrusion 11b is arranged on the inner shell 121.

[0096] In the first state, the clamping portion 121c is matched with the clamping protrusion 11b, and the accommodating device 11 limits the inner shell 121, at this time, the accommodating cavity 11a fixes the inner shell 121 immovably, and there is a certain clamping force.

[0097] In the second state, the rotating movement and the moment of the outer shell 123 can be sequentially transmitted to the inner shell 121 through the pressing member 1221 and the supporting member 1222, and drive the clamping portion 121c of the inner shell 121 to overcome the clamping force of the clamping portion 121c and the clamping protrusion 11b, so as to be separated from the clamping protrusion 11b.

[0098] Exemplarily, the clamping portion 121c is a clamping hook with an opening at one end in the rotating direction, in the second state, the outer shell 123 is rotated, and the outer shell 123 finally drives the inner shell 121 to have a rotating trend, the clamping protrusion 11b abuts against the clamping hook, when the rotating force exceeds a certain value, the clamping hook is elastically deformed, so that the clamping protrusion 11b is separated from the clamping hook through the opening, thereby releasing the clamping locking between the inner shell 121 and the accommodating device 11.

[0099] Exemplarily, the accommodating device 11 is provided with external threads, and the dispenser 12 is provided with internal threads, the dispenser 12 and the accommodating device 11 are threadedly connected through the cooperation of the external threads and the internal threads, when the clamping portion 121c of the inner shell 121 is separated from the clamping protrusion 11b, the outer shell 123 can be continuously rotated, so that the dispenser 12 and the accommodating device 11 are completely separated, and the dropper is taken out for the user to take.

[0100] Some embodiments, please refer to Figures 3 to 7 and Figure 9 The pressing member 1221 comprises a piston 12211 and a button 12212. The piston 12211 is arranged in the liquid suction channel 121a. Part of the button 12212 extends into the liquid suction channel 121a and is connected with the piston 12211. The piston 12211 and the liquid suction channel 121a are sealingly and slidably matched along the height direction of the automatic liquid suction device 10.

[0101] It should be noted that the button 12212 and the piston 12211 can be a split structure or an integrally formed structure.

[0102] Exemplarily, the button 12212 and the piston 12211 are a split structure, and are connected through clamping.

[0103] In this way, the button 12212 drives the piston 12211 to rotate and move synchronously, so as to realize the sealing and sliding fit of part of the pressing member 1221 and the liquid suction channel 121a along the height direction of the automatic liquid suction device 10.

[0104] Some embodiments, please refer to Figures 5 to 8 In the second state, the pressing member 1221 protrudes from the outer shell 123.

[0105] Exemplarily, in the first state, the top of the presser 1221 is substantially flush or completely flush with the top of the housing 123.

[0106] In this way, it is beneficial for the user to identify the state of the pumping assembly 122 and to facilitate the user to press the presser 1221.
