Description

[Technical Field]

[0001] This utility model relates to the technical field of concentrate bottles, and in particular to a dual-port negative pressure concentrate bottle. [Background Technology]

[0002] The foam cleaning pot uses the principle of jet negative pressure to draw the cleaning agent from the concentrate bottle into the water stream for mixing, then draws in air for further mixing and passes it through a high-density screen to form a dense foam cleaning solution. Existing concentrate bottles have large volumes, making handheld operation cumbersome; therefore, there is a trend towards miniaturization in concentrate bottle design.

[0003] Miniaturized concentrate bottles require frequent refilling of cleaning agent due to their small capacity. However, the replacement of concentrate bottles on the market is currently quite cumbersome and cannot improve the efficiency of replenishing cleaning agent, so their usage rate is not high.

[0004] Based on the above problems, there is an urgent need to develop a liquid concentrate bottle that can be filled with cleaning agent more quickly to improve replacement efficiency, thereby enabling the widespread use of miniaturized liquid concentrate bottles. [Utility Model Content]

[0005] The purpose of this invention is to solve the problems in the prior art by proposing a dual-port negative pressure concentrate bottle for foam pitchers, which can improve the filling efficiency of concentrate bottles.

[0006] To achieve the above objectives, this utility model proposes a dual-port negative pressure concentrate bottle for a foam pitcher, comprising a bottle body, a piston, an adapter, and a rear cover; the bottle body is hollow and forms an inner cavity; the piston is disposed in the inner cavity of the bottle body and can slide up and down, dividing the inner cavity of the bottle body into a solution cavity and a non-solution cavity, which can be switched; one end of the bottle body is provided with a first opening through which the piston can pass, and the other end is provided with a first connecting part for direct or indirect fixation to the foam pitcher; the adapter is fixed at the first opening of the bottle body, and the end of the adapter is provided with a second connecting part with the same structure as the first connecting part at one end of the bottle body, for direct or indirect fixation to the foam pitcher; the rear cover is detachably mounted on the first or second connecting part near the non-solution cavity side.

[0007] This utility model proposes another dual-port negative pressure concentrate bottle for foam pitchers, comprising a bottle body, a piston, an adapter, and a rear cover; the bottle body is hollow and forms an inner cavity; the piston is disposed in the inner cavity of the bottle body and can slide up and down, dividing the inner cavity of the bottle body into a solution cavity and a non-solution cavity, which can be switched; both ends of the bottle body are provided with a first opening for the piston to pass through; there are two adapters, which are respectively fixed at the first openings at both ends of the bottle body; the end of the adapter is provided with a second connecting part for direct or indirect fixation to the foam pitcher; the rear cover is detachably mounted on the second connecting part near the non-solution cavity side.

[0008] Preferably, the rear cover is provided with vent holes.

[0009] The beneficial effects of this utility model are as follows: This utility model has connection parts at both ends of the bottle body that can be directly or indirectly fixed to the foam pot. It has a double interface. When the original liquid in the original liquid bottle is used up, the piston slides to one end under the action of negative pressure. At this time, the cleaning agent can be directly added from the other end and connected to the foam pot, which improves the efficiency of adding cleaning agent to the original liquid bottle.

[0016] Some exemplary embodiments of this disclosure will be described in detail below with reference to the accompanying drawings and exemplary embodiments.

[0017] See Figure 1In some embodiments of this disclosure, a dual-port negative pressure concentrate bottle for a foam pitcher includes a bottle body 1, a piston 3, an adapter 2, and a rear cap 4. The bottle body 1 is hollow and has an inner cavity. The piston 3 is disposed in the inner cavity of the bottle body and can slide up and down. The friction between the piston 3 and the inner cavity wall of the bottle body is appropriate, so that when there is negative pressure on one side of the piston, the atmospheric pressure on the other side of the piston can push the piston to slide smoothly. The piston divides the inner cavity of the bottle body into a solution cavity 1b and a non-solution cavity 1c. It should be noted that the solution cavity 1b and the non-solution cavity 1c are not solid. As is constant, in the current view, after the cleaning agent in solution chamber 1b is depleted, piston 3 will slide to the top, and the volume of the current solution chamber will become zero. When adding cleaning agent again, it needs to be added from the current non-solution chamber 1c, realizing the conversion between solution chamber and non-solution chamber. One end of the bottle body is provided with a first opening 1a that allows the piston to pass through. This design takes into account the assembly process, as the piston needs to be inserted into the inner cavity from one end of the bottle body. Therefore, the inner diameter of the first opening 1a corresponds to the outer diameter of the piston. The other end of the bottle body is provided with a connection for direct or... The first connecting part 1d is indirectly fixed; it is worth noting that the structure of the connecting part 1d has various types. In one embodiment, the connecting part 1d has an external thread structure, which is directly connected to the foam bottle body through the threaded interface; in another embodiment, the connecting part 1d has a quick-connect buckle structure, which is directly connected to the foam bottle body through the buckle; in yet another embodiment, the connecting part 1d and the foam bottle body are directly connected through a set of magnetic connectors, and half of the magnetic connector is fixed to the connecting part 1d by threads; the adapter 2 is fixed at the first opening 1a of the bottle body, wherein the first An external thread is provided on the outer side of the opening 1a, and an internal thread interface 2a corresponding to the external thread on the outer side of the first opening 1a is provided on the adapter 2. The two cooperate to achieve a fixed connection. The end of the adapter is provided with a second connecting part 2b with the same structure as the connecting part 1d at one end of the bottle body, which is used for direct or indirect fixation to the foam pitcher. With this configuration, the second connecting part 2b of the adapter and the first connecting part 1d of the bottle body can be adapted and installed on the body of the foam pitcher. The rear cover is detachably installed on the first connecting part 1d or the second connecting part 2b on the side near the non-solution chamber 1c. Figure 1 In the illustrated embodiment, the rear cover is provided with a bottom cover interface 4a, and the bottom cover interface 4a is compatible with the interface specifications of the first connecting part 1d and / or the second connecting part 2b. Figure 1 The non-solution chamber 1c is close to the second connecting part 2b, so the rear cover 4 is installed on the second connecting part 2b. The rear cover is provided with a vent hole 4b, so that the non-solution chamber 1c is connected to the atmosphere.

[0018] Work process: Figure 1The negative pressure concentrate bottle shown has the foam sprayer located at its top (not shown in the figure). The negative pressure concentrate bottle is directly or indirectly fixed to the foam sprayer via the first connecting part 1d or the second connecting part 2b. A water jet is introduced into the foam sprayer to create negative pressure on the concentrate bottle. Because the non-solution chamber is connected to the atmosphere, the piston is pushed upwards, and the cleaning agent in the solution chamber 1b is carried into the flow channel of the foam sprayer to participate in foam formation. When one bottle of cleaning agent is consumed, the concentrate bottle is removed from the foam sprayer, and the rear cap 4 is removed from the second connecting part 2b. The first connector 4 is then installed onto the first connecting part 1d of the original liquid bottle, and cleaning agent is filled through the second filling port 2c of the second connecting part 2b. After filling, the second connecting part 2b is fixed onto the foam sprayer, and the operation can continue. When the cleaning agent is used up again, the rear cover 4 is removed from the first connecting part 1d and installed onto the second connecting part 2b of the original liquid bottle. Cleaning agent is then filled through the first filling port 1e of the first connecting part 1d. After filling, the first connecting part 1d is fixed onto the foam sprayer, and the operation can continue. This process can be repeated.

[0019] See Figure 2 In some embodiments of this disclosure, a dual-port negative pressure concentrate bottle for a foam pitcher includes a bottle body 1, a piston 3, an adapter 2, and a rear cover 4. The bottle body 1 is hollow and has an inner cavity. The piston 3 is disposed in the inner cavity of the bottle body and can slide up and down, dividing the inner cavity of the bottle body into a solution cavity 1b and a non-solution cavity 1c, which can be switched. Both ends of the bottle body 1 are provided with a first opening 1a that allows the piston to pass through. There are two adapters 2, which are respectively fixed at the first openings 1a at both ends of the bottle body. The end of the adapter 2 is provided with a second connecting part 2b for direct or indirect fixation to the foam pitcher. The rear cover is provided with a bottom cover interface 4a, which is compatible with the interface specifications of the second connecting part 2b. The rear cover 4 is installed on the second connecting part 2b and is provided with a vent hole 4b, so that the non-solution cavity 1c is connected to the atmosphere.
