[0002] Existing vehicles have a thermal management system. The thermal management system includes a container. The container includes a component with an opening and a cap assembly. A heat regulating fluid (e.g., coolant) can be introduced into the thermal management system from the opening. The component with the opening needs to be matched with a cap assembly so that the cap assembly can lock the bottle head and prevent people from opening it at will. Summary of the invention

[0003] Exemplary embodiments of the present application can solve at least some of the above problems. The present application provides a container. The container includes a component with an opening and a cover assembly. The component with an opening includes a main body surrounding the opening, a first protrusion and a second protrusion, the first protrusion and the second protrusion extending outward from the main body, a recess formed between the first protrusion and the second protrusion, and in a first direction, the first protrusion is located upstream of the second protrusion. The cover assembly is capable of locking or unlocking the component with an opening, and the cover assembly includes a cover and an elastic arm. The elastic arm is arranged on the cover and extends obliquely to the radial direction of the cover. In the embodiment, at least a portion of the elastic arm can be received in the recess and abuts against the second protrusion to prevent the cover assembly from rotating relative to the component with an opening in the first direction, thereby locking the cover assembly with the component with an opening; and wherein at least a portion of the elastic arm can be released from the recess to unlock the component with an opening.

[0004] According to the above container, the operating tool can abut against the elastic arm and move the elastic arm out of the recess, so that the cover assembly can rotate relative to the member having the opening in the first direction, thereby unlocking the member having the opening.

[0005] According to the above container, a guide portion is provided on the elastic arm, wherein the guide portion is configured such that when the operating tool moves along the axial direction of the cover assembly and abuts against the elastic arm, the operating tool can move the elastic arm out of the recess.

[0006] According to the above container, the operating tool abuts against the elastic arm until the cover assembly is rotated by a first preset angle along the first direction relative to the component having the opening, and the second protrusion abuts against the elastic arm, thereby preventing at least a portion of the elastic arm from being received in the recess.

[0007] According to the above container, after the cover assembly is rotated by a second preset angle relative to the component having the opening in a second direction opposite to the first direction, the first protrusion abuts against the elastic arm, thereby causing the elastic arm to move out of the recess to allow the operating tool to be inserted into the recess.

DETAILED DESCRIPTION

[0063] Various specific embodiments of the present application will be described below with reference to the accompanying drawings which constitute a part of this specification. It should be understood that in the following drawings, the same parts use the same figure numbers.

[0064] Various specific embodiments of the present application will be described below with reference to the accompanying drawings that form a part of this specification. It should be understood that although terms indicating directions, such as "upper", "lower", "left", "right", "inner", "outer", etc., are used in this application to describe various example structural parts and elements of the present application, these terms are used here only for the purpose of convenience of description, and these terms are determined based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in the present application can be set in different directions, these terms indicating directions are only for illustration and should not be regarded as limitations.

[0065] The present application provides a container, which includes a cap assembly and a container body. At least a portion of the container body forms a component with an opening. The component with an opening can be any component with an opening such as a bottle or a pipe that needs to be covered. The cap assembly can cover the opening. Further, the cap assembly of the present application can lock and unlock the component with an opening. For ease of description, in the present application, a bottle is taken as an example for introduction.

[0066] Figure 1A-1B 1 is a perspective view of the first embodiment of the cover assembly of the present application from two directions. The cover assembly is used to lock Figure 3 The bottle head 300 of the bottle shown. Figure 1A-1B As shown in FIG. 1 , the cap assembly includes a cap 102, a valve body 103, an inner cylinder 104 and a sealing ring 106. The cap 102 includes a cap top 122 and a cap side 124. Specifically, the cap top 122 is generally disc-shaped. The inner cylinder 104 extends downward from the lower surface of the cap top 122. An outer thread is provided on the outer periphery of the inner cylinder 104 for engaging with an inner thread on the bottle head 300 (see FIG. 1 ). Figure 3 ). The cover side portion 124 is formed by extending downward from the outer edge of the cover top 122 and arranged around the inner tube 104, thereby forming an annular receiving portion 173. The receiving portion 173 has a downward opening for receiving the bottle head 300. The valve body 103 is arranged below the cover top 122 and on the inner side of the inner tube 104. The valve body 103 is connected to the cover top 122. The sealing ring 106 is sleeved on the valve body 103 and is used to cooperate with the inner wall of the bottle head 300, thereby sealing the bottle head 300.

[0067] Figure 1C-1D yes Figure 1A Exploded views of the cover assembly shown from two directions. Figure 1C-1DAs shown, the valve body 103 is connected to the cap top 122 through a clamping structure. Specifically, the clamping structure includes a connecting recess 133 provided on the circumferential outer wall of the valve body 103 and a connecting protrusion 135 provided on the circumferential inner wall of the inner cylinder 104. The connecting recess 133 can receive the connecting protrusion 135, so that the valve body 103 and the cap top 122 are connected. In other embodiments, the valve body 103 can also be connected to the cap top 122 through other connecting structures (for example, welding, integral forming, etc.).

[0068] Figure 2A yes Figure 1A A perspective view of the cover 102 is shown, Figure 2B yes Figure 2A The cover 102 is shown in a cross-sectional view along line AA (ie, vertical direction). Figure 2C yes Figure 2B The cover 102 is shown in a cross-sectional view along line BB (i.e., in the horizontal direction). Figure 2A-2C As shown, the cover 102 further includes an additional peripheral portion 202, an additional top wall 204 and an extension column 206. The additional peripheral portion 202 is generally arc-shaped and is disposed on the cover side portion 124. The additional peripheral portion 202 is disposed around at least a portion of the cover side portion 124, thereby enclosing a receiving cavity 208 with a portion of the cover side portion 124. The additional top wall 204 is connected to the additional peripheral portion 202 and the cover side portion 124, thereby forming a top wall of the receiving cavity 208. The extension column 206 is formed by extending upward from the additional top wall 204 and is connected to the cover side portion 124. The top of the additional top wall 204 is flush with the cover top 122. The tool receiving through hole 210 extends in a vertical direction and penetrates the additional top wall 204 and the extension column 206. The tool receiving through hole 210 is communicated with the receiving cavity 208 for receiving an operating tool 500 (see FIG. 5). In the present embodiment, the tool receiving through hole 210 extends a distance in the circumferential direction of the cover 102 .

[0069] like Figure 2B-2C As shown, the cap assembly further includes an elastic arm 212. The elastic arm 212 is used to cooperate with the bottle head 300 to lock or unlock the bottle head 300. The elastic arm 212 is disposed in the accommodating cavity 208 and is formed by extending inward from the additional peripheral portion 202. Specifically, the elastic arm 212 extends obliquely to the radial direction of the cap 102 and is generally in an arc shape. The free end of the elastic arm 212 is used to engage with the first protrusion 304, the second protrusion 305 and the recess 306 (see Figure 3 ) to lock or unlock the bottle.

[0070] In addition, if Figure 2BAs shown, a guide portion 222 is provided on the elastic arm 212. The guide portion 222 is configured such that when the operating tool 500 (see FIG. 5 ) moves downward in the vertical direction and abuts against the elastic arm 212, the operating tool 500 can move the elastic arm 212 out of the recess 306 (see FIG. 5 ). Figure 3 In this embodiment, the guide portion 222 is disposed on the upper portion of the free end of the elastic arm 212. The guide portion 222 is an inclined surface, thereby converting the vertical downward movement (along the axial direction of the cover assembly) of the operating tool 500 into the axial movement of the elastic arm 212 away from the cover assembly.

[0071] The cap assembly of the present application can be matched with a corresponding bottle to lock or unlock the bottle.

[0072] Figure 3 It is a three-dimensional image of a portion of the bottle. Specifically, Figure 3 The bottle head 300 defining the bottle mouth is shown, so as to cooperate with the cap assembly of the present application. The rest of the bottle body is schematically shown in dotted lines. Figure 3 As shown, the bottle head 300 includes a bottle head body 302. The bottle head body 302 is generally annular and surrounds the opening 303. An internal thread is provided on the inner side wall of the bottle head body 302. The bottle head body 302 can be accommodated in the receiving portion 173. A recess 306 is provided on the bottle head 300. In this embodiment, the bottle head 300 includes a first protrusion 304 and a second protrusion 305. The first protrusion 304 and the second protrusion 305 are formed to extend outward from the bottle head body 302. In a first direction (for example, in a counterclockwise direction), the first protrusion 304 is located upstream of the second protrusion 305. The recess 306 includes a recess located between the first protrusion 304 and the second protrusion 305, for receiving at least a portion of the elastic arm 212. The cap assembly is configured such that at least a portion of the elastic arm 212 can be located in the recess 306 and abut against the side wall of the recess 306 to prevent the cap assembly from rotating relative to the bottle head in a first direction, thereby locking the bottle head. In addition, the recess 306 is also configured to accommodate an operating tool 500 (see FIG. 5 ).

[0073] Figure 4 2 is a cross-sectional view of the cap assembly and the bottle head of the present application in a locked state. Figure 4 As shown in the figure, when the cap assembly and the bottle head 300 are in a locked state, the cap assembly locks the bottle head 300. Specifically, the free end of the elastic arm 212 of the cap assembly is accommodated in the recess 306. At this time, the free end of the elastic arm 212 abuts against the second protrusion 305 to prevent the cap assembly from rotating relative to the bottle in a first direction (e.g., counterclockwise), thereby locking the cap assembly with the bottle.

[0074] It should be noted that, although the elastic arm 212 in the present application is roughly in an arc shape, any other shape of the elastic arm 212 is also within the protection scope of the present application. In addition, although the free end of the elastic arm 212 is used to be connected to the first protrusion 304, the second protrusion 305 and the recess 306 of the bottle head 300 (see Figure 3 ) to lock the bottle, but in other embodiments, at least a portion of the elastic arm 212 can abut against the second protrusion 305 to prevent the cap assembly from rotating relative to the bottle in the first direction.

[0075] In addition, reference Figure 4 and Figure 2A As shown, the tool receiving through hole 210 extends a distance in the circumferential direction of the cap 102 , so that a portion of the tool receiving through hole 210 is always aligned with the recess 306 during the process of the cap assembly rotating relative to the bottle head by a first preset angle.

[0076] Since the elastic arm 212 of the cap assembly can abut against the second protrusion 305 to prevent the cap assembly from rotating relative to the bottle in the first direction, the cap assembly locks the bottle head 300. When it is necessary to unlock the bottle head 300, the operating tool 500 needs to cooperate with the cap assembly to move the elastic arm 212 out of the recess 306 to unlock the bottle head 300. In other words, the operating tool 500 can release the elastic arm 212 from the recess 306 to unlock the bottle head 300.

[0077] The following will refer to Figure 5A-5B To describe the process of operating the tool 500 and the cap assembly to unlock the bottle head 300:

[0078] Figure 5A Yes Figure 1A-1B The cap assembly and the bottle head 300 are in a locked state, and the operating tool 500 is inserted into the recess 306 in a horizontal cross-sectional view. Figure 5A As shown, the operating tool 500 is a hexagonal column. When the bottle head needs to be unlocked, the operator inserts the operating tool 500 into the tool receiving through hole 210. During the process of the operating tool 500 moving vertically downward along the axis of the cap assembly, the operating tool 500 abuts against the guide portion 222 of the elastic arm 212, so that the operating tool 500 can enter the recess 306. During the process of the operating tool 500 entering the recess 306, the operating tool 500 abuts against the elastic arm 212 and moves the elastic arm 212 out of the recess 306. As a result, the second protrusion 305 no longer blocks the path of the elastic arm 212 rotating in the first direction, so that the cap assembly can rotate relative to the bottle head 300 in the first direction. The bottle head is no longer locked by the cap assembly, and the operator can twist the cap assembly relative to the bottle head to rotate in the first direction.

[0079] Figure 5B Yes Figure 1A-1B A cross-sectional view of the cap assembly and bottle tip 300 is shown during the unlocking process. Figure 5B The cover assembly shown is relative to Figure 5A The cap assembly shown is rotated in a first direction by a first preset angle relative to the bottle head 300. Figure 5B As shown, when the operating tool 500 is inserted into the recess 306 and abuts against the elastic arm 212, until the cap assembly is rotated relative to the bottle head 300 by a first preset angle in a first direction, the second protrusion 305 abuts against the elastic arm 212, thereby preventing at least a portion of the elastic arm 212 from being received in the recess 306. At this time, the cap assembly unlocks the bottle head 300. The operator can pull out the operating tool 500 and continue to rotate the cap assembly, thereby separating the cap assembly from the bottle head 300.

[0080] It should be noted that if Figure 5A-5B As shown, during the process of the cap assembly rotating by the first preset angle in the first direction relative to the bottle head 300, the operating tool 500 is always inserted into the recess 306 and abuts against the elastic arm 212. In other words, the operating tool 500 does not move relative to the bottle head 300. In other words, the cap assembly rotates by the first preset angle in the first direction relative to the bottle head 300 and the operating tool 500.

[0081] Therefore, the present application provides a cap assembly that can cooperate with a component having an opening (eg, a bottle body), so that a general person cannot unlock the cap assembly without a specific tool (eg, an operating tool 500).

[0082] Fig. 6A It is a stereoscopic view of the second embodiment of the cover assembly of the present application. Fig. 6A The cover assembly shown is Figure 1A-1B The same parts of the cover assembly shown are not described again. Fig. 6A The cover assembly shown is Figure 1A-1B The cover assembly shown differs in that: Fig. 6AThe cover assembly shown also includes a shielding member 602. The shielding member 602 is disposed on the cover 102 and is configured to cover the through hole 164, thereby preventing the operator from seeing the elastic arm 212 through the through hole 164. Specifically, at least a portion of the shielding member 602 can move relative to the cover 102, thereby exposing the through hole 164. In the present application, the shielding member 602 includes a shielding body 612 and a tongue 614. The shielding body 612 is roughly circular. The tongue 614 is connected to the shielding body 612 and extends radially outward from the shielding body 612 to form. The shielding body 612 is connected to the cover 102, and the tongue 614 is used to cover the through hole 164. As an example, the shielding member 602 is a plastic sheet that can be deformed. The shielding body 612 is pasted on the top surface of the cover top 122, thereby connecting with the cover 102. When no external force is applied to the shielding member 602 , the shielding body 612 and the tongue 614 are substantially in a plane. When an external force is applied to the tongue 614 , the tongue 614 can expose the through hole 164 , so that the operating tool 500 can be inserted into the through hole 164 .

[0083] It is understood that in other embodiments, the shielding member 602 can be disposed on the cover 102 in other ways. For example, the shielding member 602 is rotatably connected to the cover 102 and covers the through hole 164. When the through hole 164 needs to be exposed, the operator can rotate the shielding member 6002 by an angle.

[0084] In addition, if Fig. 6A As shown, the shielding member 602 is also provided with an information area 622. The information area 622 is used to record information related to opening the cover 102. For example, the information area records "Opening the cover is not allowed without authorization". In one embodiment, the information area records information about the bottle and / or the fluid stored in the bottle. In another embodiment, the information area is configured to facilitate the user to record information. For example, the user can fill in information in the information area.

[0085] Figure 6B It is a stereoscopic view of a third embodiment of the cover assembly of the present application. Figure 6B The cover assembly shown is Fig. 6A The same parts of the cover assembly shown are not described again. Figure 6B The cover assembly shown is Fig. 6A The cover assembly shown differs in that: Figure 6BThe shielding member 602 in the cover assembly shown is configured to cover the tool receiving through hole 210, and the shielding member 602 is configured such that: when the shielding member 602 is separated from the cover, there is a recognizable separation mark on the shielding member 602 or the cover 102, thereby prompting the operator that the tool receiving through hole 210 has been exposed. In other words, the recognizable separation mark can prompt the operator that the cover assembly may have been opened. For example, the shielding member 602 is made of a material similar to a glass film, and during the process of separating the shielding member 602 from the cover, the shielding member 602 will be slightly folded, and cracks similar to glass fragments will appear on the shielding member 602, thereby prompting the operator.

[0086] In this embodiment, a transfer area 632 is provided on the shielding member 602. The transfer area 632 displays text or patterns. When the shielding member 602 is separated from the cover, the text or pattern in the transfer area 632 is displayed on the cover 102, thereby prompting the operator. The text or pattern in the transfer area 632 is formed by a certain type of glue plus acrylic glue.

[0087] Figure 7 It is a stereoscopic diagram of the fourth embodiment of the cap assembly of the present application and the corresponding bottle head 700. Figure 7 The cover assembly shown is Figure 1A-1B The same as shown in the cover assembly and Figure 7 The bottle head 700 shown is Figure 3 The same aspects of the bottle head 300 are not described in detail. Figure 7 The bottle head 700 shown is Figure 3 The bottle head 300 shown differs in that: Figure 7 The second protrusion 305 of the bottle head 700 is provided with an additional recess 702. The recess 306 includes the additional recess 702 and a recess located between the first protrusion 304 and the second protrusion 305. The additional recess 702 is connected to the recess located between the first protrusion 304 and the second protrusion 305. The additional recess 702 has a first wall 702 extending in the radial direction, a second wall 704 perpendicular to the first wall 702 and extending along the axial direction of the bottle head 700, and a third wall 706 perpendicular to the first wall 702 and the second wall 704. The additional recess 702 is used to cooperate with the elastic arm 212. Figure 7 The cover assembly shown is Figure 1A-1B The differences in the cover assembly shown are mainly due to the combination of Figure 8 Make an introduction.

[0088] Figure 8 Yes Figure 7 The cover assembly shown is a cross-sectional view along the horizontal direction. Figure 8As shown, the elastic arm 212 is provided with a tool blocking portion 802. The tool blocking portion 802 is arranged substantially perpendicular to the axial direction of the cover assembly. In other words, the extension direction of the tool blocking portion 802 is perpendicular to the extension direction of the elastic arm 212. When the free end of the elastic arm 212 is accommodated in the recess 306, the tool blocking portion 802 is located above the recess 306 and is configured to prevent the operating tool 500 from entering the recess 306.

[0089] Fig. 9 Yes Figure 7 The cap assembly and the bottle head 700 are shown in a horizontal cross-sectional view in a locked state. Fig. 9 As shown in the figure, when the cap assembly and the bottle head 700 are in a locked state, the cap assembly locks the bottle head 700. Specifically, the free end of the elastic arm 212 of the cap assembly is accommodated in the additional recess 702. At this time, the free end of the elastic arm 212 abuts against the second protrusion 305 to prevent the cap assembly from rotating relative to the bottle in a first direction (e.g., counterclockwise). When the cap assembly and the bottle head 700 are in a locked state, the tool blocking portion 802 is located above the recess 306.

[0090] Since the elastic arm 212 of the cap assembly can abut against the second protrusion 305 to prevent the cap assembly from rotating relative to the bottle in the first direction, the cap assembly locks the bottle head 300. When it is necessary to unlock the bottle head 300, the operating tool 500 needs to cooperate with the cap assembly to move the elastic arm 212 out of the recess 306 to unlock the bottle head 300. In other words, the operating tool 500 can release the elastic arm 212 from the recess 306 to unlock the bottle head 300.

[0091] The following will refer to Figures 10A-10B To describe the partial process of the operation tool 500 cooperating with the fourth embodiment of the cap assembly to unlock the bottle head 300:

[0092] Fig. 10A Yes Figure 7 The cap assembly and the bottle head 700 are shown in a locked state, and the operating tool 500 is inserted into the recess 306 in a horizontal cross-sectional view. Fig. 10B Yes Figure 7 The cap assembly and the bottle head 700 are in a locked state, and the operating tool 500 is inserted into the recess 306 in a vertical cross-sectional view. Figures 10A-10BAs shown, the operating tool 500 is a hexagonal column. When it is necessary to unlock the bottle head 700, the operator inserts the operating tool 500 into the tool receiving through hole 210. In the process of the operating tool 500 moving vertically downward along the axis of the cap assembly until it contacts the tool blocking portion 802, the operating tool 500 abuts against the guide portion 222 of the elastic arm 212, thereby moving the elastic arm 212 out of the additional recess 702 of the recess 306. As a result, the second protrusion 305 no longer blocks the path of the elastic arm 212 rotating in the first direction. The bottle head 700 is no longer locked by the cap assembly, and the operator can twist the cap assembly relative to the bottle head 700 to rotate in the first direction, thereby unlocking the bottle head 700.

[0093] It should be noted that, since the tool blocking portion 802 is located above the recess 306 , it can prevent the operating tool 500 from entering the recess 306 after the operating tool 500 moves out of the additional recess 702 against the elastic arm 212 .

[0094] It should also be noted that, during the process of the cap assembly rotating relative to the bottle head 700 along the first direction by the first preset angle, the operating tool 500 rotates relative to the bottle head 700 along the first direction together with the cap assembly. Figure 7 The tool receiving through hole 210 provided on the cover assembly is configured to receive the operating tool 500 .

[0095] In addition, although in this embodiment, an additional recess 702 is provided on the second protrusion 305 to form a recess 306 together with the recess located between the first protrusion 304 and the second protrusion 305, in other embodiments, the bottle head 700 may not be provided with the additional recess 702.

[0096] Fig.11A is a perspective view of a fifth embodiment of the cover assembly of the present application, Fig. 11B 1 is a three-dimensional view of the cover component 1102 viewed from the inside. The similarities between the fifth embodiment of the cover assembly and the fourth embodiment of the cover assembly are not repeated here. The main differences are: Figures 11A-11BThe illustrated cover assembly further includes a covering member 1102. The covering member 1102 is mounted on the cover 102, and at least a portion of the covering member 702 can extend into the tool receiving through hole 210, thereby obstructing the operating tool 500 from entering the tool receiving through hole 210. Specifically, the covering member 1102 includes a covering body 1104 and an insert 1106. The covering body 1104 is connected to the cover 102 via a snap-fit ​​structure. The snap-fit ​​structure includes a recessed portion 1110 disposed on the cover assembly and a protrusion 1112 disposed on the covering body 1104. The recessed portion 1110 is disposed on the additional peripheral portion 202 and is formed by extending inwardly from the additional peripheral portion 202. The protrusion 1112 is formed by extending from the covering body 1104 toward the cover assembly. The protrusion 1112 can be inserted into the recessed portion 1110, thereby connecting the covering body 1104 to the cover 102.

[0097] Fig.12 is a top view of the covering member 1102. Fig.12 As shown, a through hole 1204 is provided on the cover body 1104. The insert 1106 can be inserted into the through hole 1204. The cover part 1102 also includes two breakable portions 1224. The two breakable portions 1224 are arranged on opposite sides of the insert 1106. The cover body 1104 is connected to the insert 1106 through the breakable portions 1224, and when the breakable portions 1224 are broken, the cover body 1104 and the insert 1106 are separated. A countersunk hole 1214 is provided on the top of the insert 1106. The countersunk hole 1214 is configured to receive at least a portion of the operating tool 500. In the present embodiment, the countersunk hole 1214 is substantially hexagonal so as to receive a hexagonal column. When the cap assembly and the bottle head are in a locked state, the operator can insert the insert 1106 of the cover member 1102 into the tool receiving through hole 210 and connect the cover member 1102 to the cap assembly through the snap-fit ​​structure, so that at least a portion (e.g., the lower end) of the insert 1106 extends into the tool receiving through hole 210. Before the operator needs to unlock the bottle head, the operator inserts the operating tool 500 into the counterbore 1214 and rotates the insert 1106, so that the breakable portion 1224 breaks to separate the insert 1106 from the cover body 1104. After the operator removes the insert 1106, the operator can insert the operating tool 500 into the tool receiving through hole 210 to unlock the cap assembly.

[0098] Fig.13A It is a stereoscopic view of the sixth embodiment of the cover assembly of the present application. Fig.13A The cover assembly shown is Figure 1A-1B The same parts of the cover assembly shown are not described again. Fig.13A The sixth embodiment of the cover assembly shown is Figure 3 The first embodiment of the cover assembly shown differs in that: Fig.13AThe cap assembly shown further includes a stopper 1302. The stopper 1302 is formed to extend downward from the cap side portion 124 of the cap 102 and is used to cooperate with its corresponding bottle head.

[0099] Fig. 13B It is a stereoscopic view of a bottle head 1300 that cooperates with the sixth embodiment of the cap assembly. Fig. 13B The bottle head 1300 shown is Figure 3 The same aspects of the bottle head 300 are not described in detail. Fig. 13B The bottle head 1300 shown is Figure 3 The difference of the bottle head 300 shown is that: in the axial direction of the cap assembly, the first protrusion 304 is arranged higher than the second protrusion 305. More specifically, the upper surface of the first protrusion 304 is arranged higher than the upper surface of the second protrusion 305, so that when the cap assembly is rotated relative to the bottle head 1300 in a second direction opposite to the first direction (for example, clockwise) by a second preset angle, the limiting portion 1302 can pass over the second protrusion 305 and abut against the first protrusion 304 in the circumferential direction of the assembly, thereby preventing the cap assembly from continuing to rotate relative to the bottle head 1300 in the second direction.

[0100] The following will refer to Figures 14A-14B The sixth embodiment of the cap assembly is described below, and a partial process of the operation tool 500 cooperating with the bottle head 1300 to unlock the bottle head 1300 is described below:

[0101] Fig.14A Yes Fig.13A The cover assembly shown and Fig. 13B The bottle head 1300 is shown as a cross-sectional view along the horizontal direction after being in a locked state and rotated along the second direction relative to the bottle head 1300 by a second preset angle. Fig. 14B Yes Fig.13A The cover assembly shown and Fig. 13B The bottle head 1300 shown is a cross-sectional view along the horizontal direction when the bottle head 1300 is rotated along the second direction by a second preset angle relative to the bottle head 1300 and then rotated along the first direction. Fig.14A As shown, when the bottle head 1300 needs to be unlocked, the operator rotates the cap assembly along the second direction relative to the bottle head 1300 by a second preset angle. During the rotation of the cap assembly along the second direction relative to the bottle head 1300, the first protrusion 304 abuts against the elastic arm 212, so that the elastic arm 212 moves out of the recess 306 to allow the operating tool 500 to be inserted into the recess 306.

[0102] When the cap assembly rotates relative to the bottle head 1300 along the second direction by a second preset angle, Figures 13A-13B, the limiting portion 1302 abuts against the first protrusion 304, thereby preventing the cap assembly from continuing to rotate in the second direction relative to the bottle head 1300. At this time, the operator inserts the operating tool 500 into the recess 306 through the tool receiving through hole 210. As a result, the operating tool 500 can abut against the elastic arm 212, thereby preventing the elastic arm 212 from entering the recess 306.

[0103] Then, if Fig. 14B As shown, the operator can rotate the cap assembly in the first direction relative to the bottle head 1300. At this time, the second protrusion 305 no longer blocks the path of the elastic arm 212 rotating in the first direction, so that the cap assembly can rotate in the first direction relative to the bottle head 1300, so that the bottle head 1300 is no longer locked by the cap assembly.

[0104] Fig.15A It is a stereoscopic diagram of the seventh embodiment of the cap assembly of the present application and the bottle head matched therewith. Fig.15A The cover assembly shown is Figure 7 The same as the fourth embodiment of the cover assembly shown and Fig.15A The bottle head shown is Figure 7 The similarities of the bottle heads shown are not repeated here. Fig.15A The seventh embodiment of the cover assembly shown is Figure 7 The fourth embodiment of the cover assembly shown differs in that: Fig.15A The cap assembly shown also includes a stopper, which is formed by extending downward from the cap side portion 124 of the cap 102, and the first protrusion 304 on the bottle head is arranged higher than the second protrusion 305 in the axial direction of the cap assembly, and the details can be referred to the sixth embodiment. Thus, when the cap assembly rotates relative to the bottle head in a second direction (e.g., clockwise) opposite to the first direction by a second preset angle, the stopper can pass over the second protrusion 305 and abut against the first protrusion 304, thereby preventing the cap assembly from continuing to rotate relative to the bottle head in the second direction.

[0105] The following will refer to Figures 15B-15C The seventh embodiment of the cap assembly is described below, and the operating tool 500 cooperates with the bottle head to unlock the bottle head:

[0106] Fig. 15B Yes Fig.15A The cap assembly and the bottle head are shown in a horizontal cross-sectional view after being in a locked state and rotated relative to the bottle head by a second preset angle along a second direction. Fig. 15C Yes Fig.15A The cover assembly shown and Fig. 15B The bottle head shown is a cross-sectional view along the horizontal direction when it rotates along the first direction after rotating along the second direction relative to the bottle head by a second preset angle. Fig. 15BAs shown, when the bottle head needs to be unlocked, the operator rotates the cap assembly relative to the bottle head by a second preset angle along the second direction. During the rotation of the cap assembly relative to the bottle head along the second direction, the first protrusion 304 abuts against the elastic arm 212, so that the elastic arm 212 moves out of the additional recess 702 of the recess 306, allowing the operating tool 500 to be inserted into the recess 306.

[0107] When the cap assembly rotates relative to the bottle head by a second preset angle along the second direction, the reference Fig. 15B , the limiting portion abuts against the first protrusion 304 (not shown), thereby preventing the cap assembly from continuing to rotate relative to the bottle head along the second direction. At this time, the operator inserts the operating tool 500 into the tool receiving through hole 210. At this time, the operating tool 500 can abut against the elastic arm 212.

[0108] Then, if Fig. 15C As shown, the operator can rotate the cap assembly and the operating tool 500 relative to the bottle head in the first direction. At this time, the operating tool 500 remains against the elastic arm 212, and the second protrusion 305 cannot block the elastic arm 212 from rotating in the first direction, so that the cap assembly can rotate relative to the bottle head in the first direction, so that the bottle head is no longer locked by the cap assembly.
