In addition, it should be further noted that the terms "comprises," "comprising," or any other variation thereof, are intended to cover a non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements does not include only those elements but may include other elements not expressly listed or inherent to such process, method, article, or apparatus.

Example 1

Referring to fig. 1 to 6, a liquid storage bottle 100 of a cleaning apparatus according to embodiment 1 of the present utility model is shown. The reservoir 100 of the cleaning device includes a body 11 and a cap assembly 120. The cap assembly 120 is detachably and hermetically connected to the body 11.

The bottle cap assembly 120 includes a bottle cap 12 and a flexible glue portion 13, wherein the flexible glue portion 13 is provided with at least one broken-through portion 135, and the broken-through portion 135 is exposed to the outside of the bottle cap 12 and configured to be broken through by a breaking-through structure (for example, a diversion device for diversion or an air inlet device for communicating with the atmosphere) so as to enable the liquid storage bottle 100 to be in liquid communication or gas communication with the outside. By arranging the broken-through part 135 on the flexible glue part 13 and enabling the broken-through part 135 to be at least partially exposed outside the bottle cap 12, the liquid storage bottle 100 is broken through by the convenient breaking-through structure while the liquid storage bottle 100 is sealed, and liquid in the liquid storage bottle 100 is conveniently discharged.

In this embodiment, the soft rubber portion 13 and the bottle cap 12 are separately disposed, the bottle cap 12 is in a nearly cylindrical structure, the soft rubber portion 13 is in a cylindrical shape, and the soft rubber portion 13 is disposed between the bottle body 11 and the bottle cap 12. The closure 12 includes a first side 123 facing the body 11 and a second side 124 facing away from the body 11. The diameter of the annular ring of the first side 123 is greater than the diameter of the annular ring of the second side 124. The arrangement is such that the flexible glue portion 13 is mounted in the closure 12 from the second side 124 and is retained by the annular ring of the first side 123 while being at least partially exposed from the annular ring of the first side 123 to the outside of the closure 12. In other embodiments, the soft rubber portion 13 and the bottle cap 12 may be integrally formed.

Further, the area of the flexible glue portion 13 is larger than the area of the first side 123 of the bottle cap 12, so as to close or substantially close the bottle cap 12, and prevent leakage when the liquid storage bottle 100 is horizontally placed.

The soft rubber portion 13 is provided with at least one broken-through portion 135. The broken-through portion 135 is formed by being recessed inward from the soft rubber portion 13 toward one side of the bottle cap 12. The broken-through portion 135 includes a guide portion 132 and a sealing portion 133, where the guide portion 132 is disposed away from the liquid storage bottle 100 relative to the sealing portion 133, that is, the guide portion 132 is disposed outside relative to the sealing portion 133, so that the broken-through structure can break through the sealing portion 133 through the guide portion 132 and enter the liquid storage bottle 100.

The guide portion 132 has a bell mouth shape and includes a first end 1321 and a second end 1322 disposed opposite to each other, and a cross-sectional area of the first end 1321 is smaller than a cross-sectional area of the second end 1322. Further, the cross-sectional area of the guide 132 at any point is proportional to the distance between the guide 132 and the seal 133, i.e., the cross-sectional area of the guide 132 gradually decreases from the second end 1322 to the first end 1321. So set up, when the breakthrough structure will get into stock solution bottle 100 through by breakthrough portion 135, horn mouth-shaped guiding portion 132 can guide the breakthrough structure, moreover, because the cross-sectional area of guiding portion 132 towards breakthrough structure's second end 1322 is great, even the deviation of position appears when stock solution bottle 100 installs, breakthrough structure also can be through the second end 1322 of guiding portion 132 with by breakthrough portion 135 one-to-one, thereby can insert in by breakthrough portion 135 accurately, avoid forming a plurality of sockets on bottle lid subassembly 120, influence the life of bottle lid subassembly 120, also influence the life of breakthrough structure simultaneously, because by breakthrough portion 135's position is the same position all the time, thereby can avoid liquid to leak from stock solution bottle 100. That is, the guide portion 132 can extend the service life of the breaking structure or the cap assembly, and avoid leakage.

The seal 133 is disposed at the first end 1321 and closes the first end 1321. So set up, when the flexible glue portion 13 on the bottle lid subassembly 120 is not by break through the structure and inserts, no matter how rock, seal the bottle lid subassembly 120 that the mouth 133 all can be better improves the sealed effect of bottle lid subassembly 120, is difficult for the weeping, also can be convenient for the transportation of stock solution bottle 100.

Further, the sealing portion 133 has elasticity, and the guiding portion 132 includes a first edge 1323 and a second edge 1324 that are symmetrically disposed, and at the first end 1321, a distance between the first edge 1323 and the second edge 1324 is less than or equal to an elastic deformation amount of the sealing portion 133. So set up, after the sealing part 133 is broken through by the break-through structure, pull out the break-through structure, because the elasticity deformation volume of sealing part 133 is greater than the distance of first limit 1323 and second limit 1324 at first end 1321 to make sealing part 133 can resume the original form, thereby can seal the socket that the break-through structure caused again, prevent the leakage of cleaning solution, improve sealed effect.

The sealing part 133 is provided with a connecting part 134, the connecting part 134 is arranged at one side of the sealing part 133 facing the guiding part 132, and the thickness of the connecting part 134 is smaller than that of other parts of the sealing part 133. So configured, when the break-through structure (e.g., needle) is inserted into the cap assembly 120 along the guide portion 132, the break-through structure applies a force to the seal portion 133 in a direction toward the bottle body 11, and at this time, the thickness of the connecting portion 134 is thinner than that of other portions of the seal portion 133, so that the break-through structure is easier to be pushed open, thereby facilitating the break-through structure to be inserted into the liquid storage bottle 100.

Further, the guiding portion 132, the sealing portion 133 and the connecting portion 134 are integrally formed, so as to reduce the production cost of the bottle cap assembly 120 and facilitate mass production of the bottle cap assembly 120.

The air intake 137 is configured to be breached by an air intake device to communicate the reservoir 100 with the ambient air. Preferably, the external gas may be atmospheric gas, which is introduced into the bottle body 111 of the bottle body 11 through atmospheric pressure, thereby facilitating outflow of the liquid. In other embodiments, the external air may be air with pressure formed by a pump, and the air with pressure may be positive air pressure, so as to squeeze out the liquid in the bottle 111, thereby facilitating liquid outflow. Alternatively, the air having pressure may be negative pressure, so that the pressure of the bottle 111 is smaller than the external pressure, thereby facilitating the liquid to flow out of the bottle 111 through the extrusion of the pressure. In other embodiments, the liquid outlet 136 may be included, and the air inlet 37 may be provided on the other side of the bottle body 11.

In the present embodiment, the air inlet 137 is disposed above the liquid outlet 136, so that the air guiding device is at least partially located in the air guiding portion 113 of the bottle 11 after breaking through the liquid outlet 132.

The bottle 11 includes a bottle body 111 and a bottle mouth 112, the bottle body 111 is used for storing liquid, and includes a top 1111 and a bottom 1112, and a side 1113 enclosed between the top 1111 and the bottom 1112. The finish 112 is disposed on the side 1113 and adjacent to the bottom 1112. That is, the reservoir 100 is configured to be mounted in a lateral position.

In this embodiment, the body 111 of the liquid storage bottle 100 has an approximately rectangular structure, including a top 1111 and a bottom 1112, and a side 1113 enclosed between the top 1111 and the bottom 1112. Wherein side 1113 includes a pair of oppositely disposed long side 1114 and a pair of oppositely disposed short side 1115, long side 1114 being disposed adjacent short side 1115. In other embodiments, the body 111 of the liquid storage bottle 100 may have an approximately square structure, or other polygonal structures, or may have a cylindrical structure, or at least a portion of a cylindrical structure, which is not limited by the present utility model, so long as the bottle mouth 112 of the liquid storage bottle 100 is disposed at the side 1113 (i.e. the position other than the top 1111 and the non-bottom 1112) of the liquid storage bottle 100, and the bottle mouth 112 is disposed near the bottom 1112, so as to facilitate the outflow of the liquid in the liquid storage bottle 100.

Preferably, the finish 112 is disposed on the short sidewall 1115 of the body 111 and at least partially protrudes beyond the short sidewall 1115. The first side 123 of the bottle cap 12 near one end of the bottle body 11 is provided with a first locking part 121 in a circumferential direction, which is in locking connection with the bottle body 11. Preferably, the first locking portion 121 is an internal thread provided on an inner surface of the circular ring. A second locking portion 1121 is provided on the neck finish 112 for locking connection with the cap 12. Preferably, the second locking portion 1121 is an external thread provided on the outer circumferential surface of the bottle mouth 112.

Further, a third positioning portion 1122 is further provided on the bottle mouth 112 corresponding to the first positioning portion 122, and the third positioning portion 1122 is configured to be in positioning connection with the first positioning portion 122 on the bottle cap 12, so as to perform the function of positioning and guiding the connection between the bottle cap 12 and the bottle mouth 112. In this embodiment, the third positioning portion 1122 is a groove provided on the external thread.

The bottle cap 12 is positioned and connected with the bottle mouth 112 through the first positioning part 122 and the third positioning part 1122, and is locked and connected through the first locking part 121 and the second locking part 1121.

It should be noted that the number of the first positioning portions 122, the second positioning portions 131, and the third positioning portions 1122 may be more than one, but the number of the first positioning portions 122, the second positioning portions 131, and the third positioning portions 1122 corresponds to each other.

Optionally, when the liquid is assembled into the liquid storage bottle 100, for example, when the cleaning liquid is assembled, the bottle mouth 112 of the liquid storage bottle 100 is placed upwards to add the cleaning liquid, then the second positioning portion 131 on the flexible glue portion 13 is aligned with the first positioning portion 122 on the bottle cap 12, the flexible glue portion 13 is installed into the bottle cap 12, then the first positioning portion 122 of the bottle cap 12 is aligned with the third positioning portion 1122 on the bottle mouth 112, the bottle cap 12 is buckled on the bottle mouth 112, and since the bottle cap 12 or the bottle body 111 generally has a certain elasticity (for example, both are plastic products), the bottle cap 12 can be connected to the bottle body 111 through the first locking portion 121 and the second locking portion 1121 in a locking manner, namely, the assembly is completed.

Further, a flow guiding portion 113 is disposed at a position of the bottom 1112 of the bottle 111 near the bottle opening 112, and a plane of the flow guiding portion 113 is lower than a plane of the bottom 1112. By providing the diversion portion 113, the liquid in the liquid storage bottle 100 is drained to the bottle mouth 112. Can make the liquid storage bottle 100 can directly put out liquid transversely, avoid the trouble and the design of inversion installation, reduce installation use cost. The plane of the flow guiding part 113 is lower than the plane of the bottom 1112, so that the liquid in the liquid storage bottle 100 can actively flow to the flow guiding part 113 according to the gravity of the liquid storage bottle, thereby facilitating the complete outflow of the liquid in the liquid storage bottle 100 and avoiding the residual liquid in the liquid storage bottle 100. In addition, by providing the flow guide portion 113 such that the plane in which the flow guide portion 113 is located is lower than the plane in which the bottom portion 1112 is located, the volume of the liquid storage bottle 100 can be increased, and the number of times of adding the cleaning liquid can be reduced.

Preferably, an inclined slope 1131 may be provided between the flow guiding part 113 and the bottom 1112 to facilitate the flow of liquid into the flow guiding part 113.

Further, the plane of the lowest point of the bottle opening 112 and the plane of the lowest point of the flow guiding portion 113 are located at the same horizontal plane, or the plane of the lowest point of the bottle opening 112 is lower than the plane of the lowest point of the flow guiding portion 113. That is, the finish 112 is also below the bottom 1112 of the bottle 111. So set up, make things convenient for liquid to flow from bottle 111 internal flow to bottleneck 112 voluntarily according to self gravity, improve liquid outlet efficiency.

When the diversion device breaks through the broken-through part 135 of the bottle cap assembly 120, the diversion device is at least partially inserted into the diversion part 113, so as to facilitate the liquid to flow out of the liquid storage bottle 100.

Specifically, when the deflector is inserted into the cap assembly 120, the deflector is inserted from the second end 1322 to the first end 1321 by the guide of the guide portion 132, and when the closure portion 133 is encountered, the deflector applies a force to the closure portion 133 toward the bottle body 11, and since the thickness of the connection portion 134 is thinner than other portions, the connection portion 134 is initially pushed open, but the closure portion 133 has elasticity and is integrally formed with the guide portion 132, so that the closure portion 133 remains adhered to the guide portion 132, does not fall into the bottle body 111, and does not block the deflector. When the deflector is pulled out, the sealing portion 133 is elastic and its elastic deformation amount is larger than the distance between the first edge 1323 and the second edge 1324 of the guide portion 132 at the first end, so that the sealing portion 133 will return to its original state, and the socket will be sealed again, so as to prevent the liquid from leaking out of the liquid storage bottle 100.

Further, the bottle body 111 of the liquid storage bottle 100 is provided with a picking portion 114, and the picking portion 114 is configured to pick up the liquid storage bottle 100 from the liquid storage bottle mounting mechanism 200, and when the liquid storage bottle 100 is to be picked up from the liquid storage bottle mounting mechanism 200, the picking portion 114 is used as a holding portion for convenience of a user.

In an alternative embodiment, the gripping portion 114 may be a protrusion extending outwardly from the surface of the bottle 111. The protrusions may cooperate with corresponding structures on the reservoir mounting mechanism 200 to play a role in mounting and securing the reservoir 100 while facilitating removal of the reservoir 100. In addition, by providing the pick-up portion 114 as a protrusion, the volume of the liquid storage bottle 100 can be further increased. In other embodiments, the picking part 114 may have other structures, for example, a groove recessed (inward recessed) from the bottom 1112 toward the top 1111, or the picking part 114 may be a tab provided on the bottom 1112, or the picking part 114 may be a hollow handle, so long as the convenience of the user for picking is satisfied.

In an alternative embodiment, the gripping portion 114 is a protrusion extending from the base 1112 in a direction away from the base 1112. The protrusion may be positioned at a location on the base 1112 that is not proximate to the finish 112. Preferably, the protrusions are provided on the side of the base 1112 remote from the finish 112. By the arrangement, the liquid storage bottle 100 can be conveniently and fixedly installed when being installed on the liquid storage bottle installation mechanism 200, and the liquid storage bottle 100 can be conveniently held by a user and supported by providing force for the user to pull out the liquid storage bottle 100 when being taken out. In other embodiments, the protrusion may be provided on the top 1111 or the side 1113 remote from the finish 112, as the utility model is not limited in this regard.

Further, the height of the liquid storage bottle 100 is equal to or less than the width of the liquid storage bottle 100. Since the liquid storage bottle 100 is horizontally installed and horizontally discharged, the height of the liquid storage bottle 100 is not necessarily set too high, so that the height of the liquid storage bottle installation mechanism 200 can be reduced, the height of the base station 300 having the liquid storage bottle installation mechanism 200 can be further reduced, or more space for installing other structures in the height direction can be provided for the base station 300.

Example 2

The bottle cap assembly 120 in embodiment 2 is substantially the same as the liquid bottle 100 of the cleaning apparatus as in embodiment 1, except that the structure of the broken-through portion 135 on the soft rubber portion 13 is different. The following description is only specific to different structures, and the same structures are not repeated here.

Referring to fig. 7 to 9, the liquid storage bottle 100 includes a bottle body 11 and a bottle cap assembly 120.

The bottle cap assembly 120 includes a bottle cap 12 and a flexible glue portion 13, wherein the flexible glue portion 13 is provided with at least one broken-through portion 135, and the broken-through portion 135 is exposed to the outside of the bottle cap 12 and configured to be broken through by a breaking-through structure (for example, a diversion device for diversion or an air inlet device for communicating with the atmosphere) so as to enable the liquid storage bottle 100 to be in liquid communication or gas communication with the outside. By arranging the broken-through part 135 on the flexible glue part 13 and enabling the broken-through part 135 to be at least partially exposed outside the bottle cap 12, the liquid storage bottle 100 is broken through by the convenient breaking-through structure while the liquid storage bottle 100 is sealed, and liquid in the liquid storage bottle 100 is conveniently discharged.

The soft rubber portion 13 is provided with at least one broken-through portion 135. The broken-through portion 135 includes a guide portion 132 and a sealing portion 133, and the guide portion 132 is disposed away from the liquid storage bottle 100 with respect to the sealing portion 133.

The guide portion 132 has a bell mouth shape and includes a first end 1321 and a second end 1322 disposed opposite to each other, and a cross-sectional area of the first end 1321 is smaller than a cross-sectional area of the second end 1322. Further, the cross-sectional area of the guide 132 at any point is proportional to the distance between the guide 132 and the seal 133, i.e., the cross-sectional area of the guide 132 gradually decreases from the second end 1322 to the first end 1321. So set up, when the breakthrough structure will get into stock solution bottle 100 through by breakthrough portion 135, horn mouth-shaped guiding portion 132 can guide the breakthrough structure, moreover, because the cross-sectional area of guiding portion 132 towards breakthrough structure's second end 1322 is great, even the deviation of position appears when stock solution bottle 100 installs, breakthrough structure also can be through the second end 1322 of guiding portion 132 with by breakthrough portion 135 one-to-one, thereby can insert in by breakthrough portion 135 accurately, avoid forming a plurality of sockets on bottle lid subassembly 120, influence the life of bottle lid subassembly 120, also influence the life of breakthrough structure simultaneously, because by breakthrough portion 135's position is the same position all the time, thereby can avoid liquid to leak from stock solution bottle 100. That is, the guide portion 132 can extend the service life of the breaking structure or the cap assembly, and avoid leakage.

Further, the connection portion 134 does not overlap with the projection of the first end 1321 on the sealing portion 133. That is, the connection portion 134 is not disposed at the connection between the first end 1321 of the guide portion 132 and the sealing portion 133, but is disposed at a position where the sealing portion 133 is close to the bottle body 111 with respect to the first end 1321. This is arranged such that the connection portion 135 is spaced from the first end 1321 to facilitate accurate insertion of a fluid guiding device, such as a needle, into the sealing portion 133.

In the present embodiment, the breached portion 135 includes a liquid outlet 136 and an air inlet 137. The liquid outlet 135 is configured to be broken through by the flow guiding device, so that the liquid in the liquid storage bottle 100 flows out through the liquid outlet 135. The air intake 137 is configured to be breached by an air intake device to communicate the reservoir 100 with the ambient air. The liquid outlet 136 is disposed below the air inlet 137. In other embodiments, the number of liquid outlet 136 and air inlet 137 may not be limited, or the breached portion 135 may include only the liquid outlet 136, with the air inlet 137 being disposed elsewhere on the body 11.

When the guiding device is inserted into the bottle cap assembly 120, the guiding device is inserted from the second end 1322 to the first end 1321 through the guiding of the guiding portion 132, and when the sealing portion 133 is encountered, the connecting portion 134 is not disposed at the connection between the guiding portion 132 and the sealing portion 133, so that the guiding device firstly opens the first sealing piece 1331 and the second sealing piece 1332, which are not connected with the sealing portion 133, and then pierces the connecting portion 134, so that the guiding device can be accurately inserted into the guiding portion 113 of the bottle body 11 through the sealing portion 133, thereby facilitating the liquid to flow out of the liquid storage bottle 100. The sealing portion 133, the connecting portion 134 and the guiding portion 132 are integrally formed, so that the connecting portion 134 is still adhered to the first sealing member 1331 and the second sealing member 1332 after being broken, and does not fall into the bottle 111 and block the flow guiding device. When the diversion device is pulled out, the sealing part 133 has elasticity, and the distance between the first edge 1323 and the second edge 1324 at the first end 1321 is less than or equal to the sum of the thicknesses of the first sealing part 1331 and the second sealing part 1332, so that the sealing part 133 can return to the original state, and the socket is sealed again, so that the liquid is prevented from leaking out of the liquid storage bottle 100.
