As shown in fig. 3-4, the liquid storage device 11 includes an inverted liquid outlet pump head and a liquid storage tank 112, the liquid storage tank 112 is used for storing soap, the soap may be hand sanitizer, hand washing gel, disinfectant, shampoo, body wash, or other types of soap or gel, as shown in fig. 5, a mounting channel 1124 communicated with the inside of the bottom (the bottom corresponds to the top of the liquid storage tank 112 shown in fig. 5) of the liquid storage tank 112 is provided, the inverted liquid outlet pump head is mounted on the mounting channel 1124, and the soap in the liquid storage tank 112 is pumped out by pressing the inverted liquid outlet pump head.

Wherein, the inverted liquid outlet pump head comprises a press type liquid suction assembly 111, it can be understood that the press type liquid suction assembly 111 is a conventional mechanism for sucking the soap liquid in the liquid storage tank 112 out of the liquid storage tank 112 by using pressure difference, and generally comprises a liquid guide tube 1111, a liquid inlet ball valve, a spring, a hollow plunger, a piston, a liquid storage cylinder, a liquid outlet pipe 1112, a press part 1113 and the like, when liquid is discharged by pressing, the pressure in the liquid storage cylinder is increased, the spring is compressed, the liquid inlet valve is closed, meanwhile, the piston moves upwards, a liquid outlet hole on the hollow plunger is opened, the soap liquid in the liquid storage cylinder flows out of the liquid outlet pipe 1112 from the liquid storage cylinder, when a hand is loosened, the spring is restored, so that the piston moves downwards, the pressure in the liquid storage cylinder is reduced, the liquid outlet hole on the hollow plunger is closed, meanwhile, the liquid inlet valve is opened, the soap liquid enters the liquid storage cylinder from the liquid guide tube 1111 through the liquid inlet valve under the action of atmospheric pressure, thus, the piston is caused to reciprocate up and down in the reservoir by applying a force to the pressing member 1113, and the soap liquid is continuously sucked out of the reservoir 112.

As shown in FIG. 4, in this embodiment, the liquid guiding tube 1111 is disposed on the top of the pressing type liquid absorbing assembly 111, and the liquid guiding tube 1111 is located in the liquid storage tank 112, and the liquid inlet of the liquid guiding tube 1111 is as close as possible to the inner bottom wall of the liquid storage tank 112 or to the installation channel 1124, so as to minimize the amount of the final residual liquid soap in the liquid storage tank 112 and to make it as much as possible to be used up, thereby avoiding waste of liquid soap and saving resources.

With continued reference to fig. 3-4, as a preferred embodiment, the inverted liquid outlet pump head further includes an end cap 113, the end cap 113 is mounted on the end of the liquid guiding tube 1111 in a forward mounting manner, a liquid inlet channel is formed between the end cap 113 and the liquid guiding tube 1111, the liquid inlet channel communicates with the liquid guiding tube 1111 and the interior of the liquid storage tube 112, so that the soap liquid in the liquid storage tube 112 can enter the interior of the push-type liquid absorbing assembly 111 through the liquid inlet channel, wherein the liquid inlet of the liquid inlet channel is located at the bottom or side of the end cap 113, and the liquid inlet of the liquid inlet channel is located near the bottom wall of the interior of the liquid storage tube 112 or near the mounting channel 1124 or in the mounting channel 1124.

Because the length of the liquid guiding tube 1111 of the commercially available pressing type liquid absorbing assembly 111 is generally set to be longer or the length of the pressing type liquid absorbing assembly 111 is longer due to the structure (specifically, for example, a certain amount of soap liquid needs to be stored in the liquid storage cylinder, so a certain length must be preset, so the whole structure must be preset), which results in a longer distance between the liquid inlet of the liquid guiding tube 1111 and the inner bottom wall of the liquid storage cylinder 112 or the installation channel 1124. on the basis of not changing the original structure of the liquid absorbing assembly 111, the pressing type liquid absorbing assembly can make the liquid inlet of the liquid guiding tube 1111 indirectly close to the installation channel 1124 or in the installation channel 1124 by adding the end cap 113 installed in the forward direction at the end of the liquid guiding tube 1111 and making the liquid inlet close to the inner bottom wall of the liquid storage cylinder 112 or close to the installation channel 1124 or in the installation channel 1124 as much as possible by using the end cap 113 to change the orientation of the liquid inlet, so as to reduce the final residual soap liquid amount in the liquid storage tank 112 to the minimum and to be used up as much as possible, avoid wasting the soap liquid and save resources.

Of course, the liquid inlet channel may be directly opened on the wall of the mounting cavity 1131 or the outer side wall of the liquid guide tube 1111 as long as the liquid inlet channel can communicate with the interior of the liquid storage tank 112 and the liquid guide tube 1111.

Referring to fig. 6, more specifically, in order to make the connection between the end cap 113 and the liquid guide tube 1111 more reliable, the bottom wall of the mounting cavity 1131 is provided with a slot 11331 tightly fitted with the end of the liquid guide tube 1111, and the end of the liquid guide tube 1111 is spaced from the bottom wall of the mounting cavity 1131, so that the liquid inlet channel is communicated with the liquid guide tube 1111.

With reference to fig. 6, more specifically, in order to space the end of the catheter 1111 from the bottom wall of the mounting cavity 1131, the bottom wall of the mounting cavity 1131 is configured with at least one mounting plate 1133, and the mounting plate 1133 is configured with two slots 11331 arranged at intervals, so that the two opposite sides of the catheter 1111 are respectively matched with the two slots 11331, and the connection is more reliable.

In a preferred embodiment, the mounting plate 1133 is configured with two pieces, and the two mounting plates 1133 are staggered to make the connection between the end cap 113 and the catheter 1111 more reliable.

It can be understood that, in order to allow the liquid storage device 11 to be normally supplied with air when inverted, the total amount of the soap liquid in the liquid storage tank 112 should be smaller than the total volume of the liquid storage tank 112, for example, the total volume of the liquid storage tank 112 is 1400 ml, and the total amount of the soap liquid in the liquid storage tank 112 is 1200 ml, so that a certain gap is left between the highest liquid level of the soap liquid in the liquid storage tank 112 and the top inner wall of the liquid storage tank 112 when inverted, so that the blocking cover 114 is not immersed in the soap liquid, so that the external pressure can push the blocking cover 114 and open the blocking cover 114, when working, because the pressure in the liquid storage tank 112 is lower than the external atmospheric pressure, the blocking cover 114 is pushed to open by using the external atmospheric pressure, so that the external air enters the liquid storage tank 112 to balance the internal air pressure, and the soap liquid in the liquid storage tank 112 can be smoothly pumped out of the liquid storage tank under the action of the liquid suction pressing assembly 111.

As a preferred embodiment, referring to fig. 5, the liquid storage tank 112 is provided with a mounting hole 1122, referring to fig. 8, the blocking cover 114 specifically includes a blocking portion 1141, a connecting portion 1142 and a limiting portion 1143, the blocking portion 1141 is located in the liquid storage tank 112 and is used for blocking the air inlet hole 1121, the blocking portion 1141 can be switched between a closed state of being attached to an inner wall of the liquid storage tank 112 to block the air inlet hole 1121 and an open state of being formed with a gap with the inner wall of the liquid storage tank 112 to open the air inlet hole 1121, a first end of the connecting portion 1142 is connected to the blocking portion 1141, a second end of the connecting portion 1142 passes through the mounting hole 1122, the limiting portion 1143 is disposed on the connecting portion 1142 and abuts against an outer wall of the liquid storage tank 112 to limit the blocking portion 1141 and prevent the blocking cover 114 from moving up and down, so as to reliably mount the blocking cover 114 on the liquid storage tank 112.

Continuing to refer to fig. 5, more specifically, the inner wall of the liquid storage tank 112 is configured with a boss 1123, the bottom of the boss 1123 is a first plane 11232, the mounting hole 1122 is located on the first plane 11232, the boss 1123 forms a curved positioning surface 11231 at a position close to the side portion of the bottom of the boss 1123, the air inlet hole 1121 is located on the curved positioning surface 11231, the blocking portion 1141 is formed with a groove 11411 recessed from top to bottom and having a curved inner wall, the groove 11411 can be attached to the curved positioning surface 11231, and the bottom wall of the groove 11411 is a second plane 11412 attached to the first plane 11232, so that, in a non-working state, the attachment of the groove 11411 to the curved positioning surface 11231 can function to seal the air inlet hole 1121, while the attachment of the second plane 11412 to the first plane 11232 can function to seal the mounting hole 1122, thereby better preventing the soap liquid in the liquid storage tank 112 from leaking out, and meanwhile, the groove 11411 having a better tension force on the curved inner wall, so that the attachment of the blocking portion 1141 to the boss 1123 can be more reliable, when the liquid storage tank 112 works, the air inlet hole 1121 is coated by the outer side part of the blocking part 1141, and under the action of the difference between the internal pressure and the external pressure, the outer side part of the blocking part 1141 is more easily pushed away by the external pressure because the outer side part is not limited by the connecting part 1142 and the limiting part 1143, so that a gap is more easily formed between the outer side part of the blocking part 1141 and the boss 1123, and the gap is used for communicating the inside of the liquid storage tank 112 and the air inlet hole 1121, so that external air can enter.

More specifically, the air inlet hole 1121 is formed at a position at or near the top side of the liquid storage tank 112 when the liquid storage tank is inverted, so that the valve disposed on the air inlet hole 1121 can be ensured to function as a blocking cover 114, and at the same time, the liquid storage tank 112 can be filled with more soap.

More specifically, the blocking cover 114 may be made of a flexible material with a certain supporting force, such as a rubber material, a silica gel material, or a plastic material, so that the blocking portion 1141 of the blocking cover 114 can be deformed more easily under the action of external pressure, and thus the blocking portion 1141 can be pushed open more easily, and a gap for gas to enter can be formed between the blocking portion 1141 and the inner wall of the liquid storage tank 112, meanwhile, the blocking cover 114 made of the flexible material with a certain supporting force can be better attached to the inner wall of the liquid storage tank 112, so as to achieve reliable closing of the blocking cover 114 and avoid leakage of soap solution, or when the blocking cover 114 is made of a hard material, the blocking portion 1141 is preferably made into a thin-walled structure, so that it has a certain elasticity.
