technical field

The invention belongs to the technical field of health care, and in particular relates to a container bottle and a nursing instrument.

Background technique

With the development of products in the field of personal care, people pay more and more attention to the care and maintenance from appearance to inner health of the body. A container bottle for storing liquids (such as emollient oil, face cream and essential oil) is generally set inside the nursing device. The container bottle is fixed in the nursing device, and the delivery pump is connected with a catheter. The catheter penetrates into the container bottle to absorb the liquid. Under this design, when the liquid level of the container bottle is lower than the port of the catheter, it is difficult for the delivery pump to suck the liquid, thereby causing the problem of liquid residue. In addition, when there is still a certain amount of liquid in the container bottle, the liquid level in the container bottle may be lower than the port of the catheter due to the tilting or inversion of the nursing device, making it difficult for the liquid to be sucked by the delivery pump. In this case, the nursing device is placed in the forward position, and the delivery pump can absorb the liquid. Therefore, the design limits the use state of the nursing device.

Example 1

As shown in FIGS. 1 to 4 , an embodiment of the present application provides a container bottle 10 , which is matched with a delivery pump. For the structure of the delivery pump, please refer to the delivery pump 54 in the second embodiment.

The container bottle 10 is used for accommodating liquid, and the delivery pump can pump out the liquid in the container bottle 10 when it cooperates with the container bottle 10 .

The container bottle 10 includes a bottle body 11 and a piston 12 .

The bottle body 11 has an accommodating cavity, and the piston 12 is arranged in the accommodating cavity. The piston 12 divides the accommodating chamber into a liquid-storage chamber 101 and an adjustment chamber 102 arranged up and down. The liquid-storage chamber 101 is a water-tight chamber and is used to accommodate liquid. The adjustment chamber 102 communicates with the atmosphere.

The bottle body 11 is provided with a communication hole 103 extending upward to the upper surface of the bottle body 11 in the upper cavity wall of the liquid-storage cavity 101 .

Wherein, the communication hole 103 can cooperate with the delivery pump, so that the delivery pump can provide negative pressure/positive pressure to the liquid-storage chamber 101 to drive the piston 12 to move up/down relative to the bottle body 11 . In this embodiment, the cooperation between the communication hole 103 and the delivery pump means that the delivery pump can act on the communication hole 103 to provide negative pressure or positive pressure to the nano-liquid chamber 101 .

The piston 12 is connected with the bottle body 11 in a watertight manner, so that the liquid-storage cavity 101 is a watertight cavity. Specifically, the piston 12 includes a support member supported by a rigid material and a rubber sleeve sleeved on the support member. The rubber sleeve is in an interference fit with the accommodating cavity to achieve water tightness between the rubber sleeve and the bottle body 11 . Those skilled in the art can understand that the piston 12 has a certain height in the up-down direction, and combined with the cooperation between the piston 12 and the bottle body 11, ensures that the piston 12 moves up and down in the accommodating cavity without deflection.

When the delivery pump cooperates with the communication hole 103, the delivery pump applies a negative pressure to the liquid-storage chamber 101. Since the adjustment chamber 102 is communicated with the atmosphere, the piston 12 moves upward under the action of the negative pressure, and the space of the liquid-storage chamber 101 is reduced.

The communication hole 103 can be used for the inflow and outflow of liquid. In use, the operator can pour liquid into the liquid-storage cavity 101 through the communication hole 103, and the piston 12 moves downward under the action of the liquid gravity until it abuts against the lower cavity wall of the accommodating cavity. When the liquid needs to be pumped, the delivery pump is connected to the communication hole 103 , and negative pressure is applied to the liquid-storage chamber 101 , and the piston 12 moves upward to push the liquid in the liquid-storage chamber 101 out of the communication hole 103 .

The container bottle 10 provided in this embodiment is an independent structure, and can cooperate with the delivery pump to output liquid under the action of the delivery pump. Especially when used in the fields of aromatherapy and nursing, the container bottle 10 is designed as an independent structure, that is, the container bottle 10 can be replaced. When the liquid in the container bottle 10 is used up, the container bottle 10 can be replaced without discarding the entire aromatherapy device. Or care equipment, that is, aromatherapy or care equipment, by replacing the container bottle 10, the structures other than the container bottle 10 can be used for a long time, thereby improving the utilization of resources. When the liquid in the container bottle 10 is used up, the container bottle 10 can also be separated from the overall structure and then filled with liquid through the communication hole 103, so that the container bottle 10 itself can be reused, and the utilization rate of resources can be further improved.

In the container bottle 10 provided in this embodiment, when the piston 12 moves upward, the liquid in the liquid-storage chamber 101 is squeezed out from the communication hole 103 . Since the communication hole 103 is opened on the upper cavity wall of the nano-liquid cavity 101 and extends to the upper surface of the bottle body 11, the upper surface of the piston 12 and the upper cavity wall of the accommodating cavity are enclosed to form the nano-liquid cavity 101. The shape of the upper cavity wall of the accommodating cavity is matched. In theory, when the piston 12 moves upward to abut against the upper cavity wall of the liquid-storage cavity 101, the liquid in the liquid-storage cavity 101 can be completely squeezed out of the liquid-storage cavity 101. It will not produce residual liquid, thereby improving the utilization rate of liquid. In addition, because the communication hole 103 is opened on the upper cavity wall of the liquid-storage chamber 101, the piston 12 moves upward to push the liquid out of the communication hole 103, and there is no conduit or other obstacles, so it will not be affected by the use state of the entire device. That is, no matter whether the device is placed forwardly, reversely or obliquely during use, the delivery pump cooperates with the communication hole 103 to drive the piston 12 to move upward to squeeze out the liquid.

Based on the above analysis, the container bottle 10 provided in this embodiment will not be affected by the use state when used in conjunction with the delivery pump, and can discharge or inject the liquid in the liquid-storage chamber 101 no matter it is placed at any angle, thereby solving the problem of using The state is limited and the container bottle 10 is prone to the problem of residual liquid.

In another embodiment of the present application, the communication hole 103 can also cooperate with the delivery pump, so that the delivery pump provides positive pressure to the liquid-storage chamber 101 to drive the piston 12 to move downward relative to the bottle body 11 . The delivery pump applies positive pressure to the nano-liquid chamber 101, the piston 12 will move downward, and the space of the nano-liquid chamber 101 increases accordingly. In actual use, the delivery pump can directly pump liquid into the liquid-receiving cavity 101 through the communication hole 103 until the piston 12 abuts against the lower cavity wall of the accommodating cavity.

In another embodiment of the present application, the container bottle 10 further includes a connection joint 13 provided on the bottle body 11 , and the connection joint 13 has an infusion channel 105 communicated with the communication hole 103 and a connection port 106 communicated with the infusion channel 105 . The port 106 is used to cooperate with the delivery pump for the delivery pump to provide negative pressure or positive pressure to the liquid-storage chamber 101 . Specifically, the delivery pump and the connection joint 13 can be detachably connected through the connection structure, or an installation cavity for fixing the delivery pump and the container bottle 10 can be provided on the installation shell 51 of the aromatherapy or nursing equipment, that is, through the specific installation of the installation shell 51. The structural arrangement realizes the fixation of the relative positions of the delivery pump and the container bottle 10 so that the communication hole 103 is matched with the delivery pump.

The connection port 106, the infusion channel 105, the communication hole 103 and the nano-liquid cavity 101 communicate with each other, and the delivery pump is connected to the connection port 106 to provide negative pressure or positive pressure to the nano-liquid cavity 101, thereby driving the piston 12 to move up or down, while The liquid in the nano-liquid cavity 101 is squeezed out or the liquid is input into the nano-liquid cavity 101 .

The setting of the connection joint 13 transfers the surface that cooperates with the delivery pump from the communication hole 103 to the connection port 106. One end of the connection joint 13 is connected to the bottle body 11 and the other end is abutted or connected with the delivery pump. The connection joint 13 can be adjusted according to the delivery pump. The structure adjustment design is carried out with the structure of the bottle body 11 to reduce the difficulty of production matching between the delivery pump and the communication hole 103 . In this embodiment, the extension path of the conveying channel 105 is set in a folded line, and the corner is a right angle. In other embodiments, the extension path of the conveying channel 105 may be arc, straight, curved, etc., which is not limited here. The cross section of the conveying channel 105 may be circular, oval, square or other shapes, which are not limited herein. The conveying channel 105 may be designed with a constant cross-section or a variable cross-section design, which is not limited herein. .

In another embodiment of the present application, the upper surface of the piston 12 is conical, the shape of the upper cavity wall of the nano-liquid chamber 101 is matched with the piston 12 , and the communication hole 103 is disposed near the center of the nano-liquid chamber 101 . In the illustrated structure, the shape of the accommodating cavity can be regarded as a cylindrical cavity extending up and down superimposed with a conical cavity. Correspondingly, the part where the piston 12 abuts against the accommodating cavity is cylindrical, and the upper part is a cylinder. conical. When the piston 12 moves upward to reach the conical cavity and continues to move upward, the liquid is concentrated in the middle, and the communication hole 103 is close to the center of the liquid nano cavity 101 to facilitate the liquid to be drained. Theoretically, the communication hole 103 is arranged at the center (central axis) of the liquid-storage chamber 101, which can achieve the best liquid draining effect. In this embodiment, the communication hole 103 is set close to the center of the nano-liquid cavity 101 within a radius range of 1/2 of the distance between the communication hole 103 and the center. Those skilled in the art can further set the distance between the communication hole 103 and the center to be less than 1/4 radius range or less than 1/6 radius range.

In another embodiment of the present application, please refer to FIG. 4 , the bottle body 11 includes a bottle body 111 and a bottle cap 112 , and the bottle body 111 and the bottle cap 112 are detachably connected and enclosed to form a accommodating cavity.
