DETAILED DESCRIPTION

[0032] The exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present invention are shown in the accompanying drawings, it should be understood that the present invention can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided to enable a more thorough understanding of the present invention and to fully convey the scope of the present invention to those skilled in the art.

[0033] The embodiment of the utility model provides a disinfectant bottle with sealing performance, such as Figure 1-6 As shown, it comprises: a bottle body 1, a pumping device 2 connected to the bottle body 1; the pumping device 2 comprises: a pressing head 21, a piston 22, a sealing ball 23, a shell 24, a dip tube 25, and a pump ball 26;

[0034] The pressing head 21 has a through hole suitable for the circulation of disinfectant; one end of the piston 22 is a fixed end 221, and the other end is a piston head 222, and the inside has a channel 223 that penetrates the through hole; the fixed end 221 is fixedly connected to the pressing head 21; the sealing ball 23 is arranged at the fixed end 221, and can be movably embedded in the channel 223, and is suitable for moving between the through hole and the channel 223; the shell 24 is sleeved on the outside of the piston 22, including a mounting portion and a chamber 241; the mounting portion is connected to the bottle body 1 and is movably connected to the pressing head 21; the chamber 241 is suitable for accommodating the reciprocating movement of the piston head 222; the dipping tube 25 is connected to the chamber 241; the pump ball 26 is located at the connection between the chamber 241 and the dipping tube 25.

[0035] In the sealed disinfectant bottle described in this embodiment, the pressing head 21, the piston 22, the chamber 241, and the dipping tube 25 are connected through and through, forming a flow channel for the disinfectant in the bottle body 1 to be pumped to the external environment. When the sealing ball 23 is embedded in the channel 223, the flow channel can be sealed to prevent the disinfectant in the bottle body 1 from volatilizing to the outside of the bottle through the pumping device 2 and to prevent the air in the external environment from entering the chamber 241. When the pump ball 26 is in a static position, it can seal the connection between the chamber 241 and the dipping tube 25 to prevent the disinfectant in the chamber 241 from flowing back into the bottle body 1, and further reduce the loss of volatile substances in the disinfectant in the bottle body 1.

[0036] As a preferred implementation of this embodiment, the through hole of the pressing head 21 includes a first channel 211 and a second channel 212 that are interconnected; the first channel 211 is perpendicular to the second channel 212, and the inner diameter of the first channel 211 is smaller than the inner diameter of the second channel 221. In this embodiment, the first channel 211 is arranged horizontally to facilitate the pressing of the pressing head 21. The diameter of the sealing ball 23 is larger than the inner diameter of the first channel 211 and smaller than the inner diameter of the second channel 212. This arrangement can ensure that the sealing ball 23 reciprocates in the second channel 212 without entering the first channel 211.

[0037] As a preferred implementation of this embodiment, a slope is provided at the fixed end 221, and the slope extends from the second hole 212 to the channel 223 and is connected with the second hole 212; the diameter of the sealing ball 23 is larger than the inner diameter of the channel 223, and is suitable for being movably embedded in the slope and moving between the slope and the second hole 212. In this way, when the sealing ball 23 moves between the through hole and the channel 223, the slope can make the movement trajectory of the sealing ball 23 more controllable, and when the sealing ball 23 is in a stationary position, it can be embedded in the slope, and play a good sealing role.

[0038] For achieving the purpose of the utility model, the shell 24 only needs to be installed on the bottle body 1 and can achieve sealing. In this embodiment, a preferred implementation is provided, the mounting portion of the shell 24 includes a bottle body mounting groove 242; the bottle body mounting groove 242 is suitable for threaded connection with the bottle mouth of the bottle body 1, such as Figure 4 shown.

[0039] As a preferred design mode of this embodiment, the mounting portion of the housing 24 further includes a limiting tube 243; the limiting tube 243 is located between the piston 22 and the bottle mounting groove 242, and is suitable for being inserted into the limiting groove 213 of the pressing head 21, so that the housing 24 is movably connected with the pressing head 21. On the one hand, the setting of the limiting tube 243 and the limiting groove 213 can realize the movably connection between the pressing head 21 and the housing 24, and on the other hand, when the pressing head 21 moves downward, the limiting tube 243 can limit the moving distance of the pressing head 21.

[0040] As a preferred implementation of this embodiment, the mounting portion of the housing 24 further includes a limit seat 244; the limit seat 244 is disposed at the end of the limit tube 243 and is suitable for limiting the position of the piston head 222. When the piston 22 moves downward, the limit seat 244 limits the moving distance of the piston 22, so that the piston head 222 moves within the limited range of the chamber 241.

[0041] For achieving the purpose of the present invention, the chamber 241 and the dip tube 25 can be connected in a through manner, and those skilled in the art can adopt any connection method. In this embodiment, a specific design method is provided, wherein the housing 24 further includes an extension tube 245, which is located at the end of the chamber 241 and is suitable for being fixedly connected to the dip tube 25. Figure 5 As shown, the inner diameter of the extension tube 245 is slightly larger than the outer diameter of the dip tube 25 , so that the dip tube 25 can be inserted into the extension tube 245 to achieve a through connection between the dip tube 25 and the chamber 241 .

[0042] As a preferred implementation of this embodiment, the pumping device 2 further includes a spring 27, which is sleeved outside the piston 22 and located inside the position limiting tube 243; one end of the spring 27 abuts against the pressing head 21, and the other end abuts against the position limiting seat 244. The setting of the spring 27 can provide a restoring force for the pressing head 21, so that the pressed pressing head 21 automatically returns to the initial position.

[0043] As a preferred implementation of this embodiment, the sealed disinfectant bottle further includes a pump ball cover 28, which is provided with a hole and is covered above the pump ball 26. The provision of the pump column cover 28 can prevent the pump ball 26 from rolling at any position in the chamber 241, so that the pump ball 26 always reciprocates at the connection between the dip tube 25 and the chamber 241. For achieving the purpose of the utility model, the shape of the pump column cover 28 is not unique, as long as it can limit the pump ball 26 and allow the disinfectant to pass through, for example, Figure 3As shown, the portion of the pump ball cover 28 located in the chamber 241 is a hollow frustum, and a mesh structure that fits the pump ball 26 can be provided below the pump ball 26 .

[0044] As a preferred implementation of this embodiment, the sealed disinfectant bottle further includes a sealing cover 3, which is snapped onto the through-hole end of the pressing head 21 to prevent the disinfectant from volatilizing from the through-hole end of the pressing head, thereby increasing the sealing of the sealed disinfectant bottle. For achieving the purpose of the utility model, the shape of the sealing cover 3 is not unique. In this embodiment, as Figure 3 As shown, the sealing cover 3 is a cuboid with a rectangular opening on one side, and the rectangular opening fits the shape of the through hole end of the pressing head 21 and is suitable for snap-fit ​​connection.

[0045] The working process of the sealed disinfectant bottle described in this embodiment is as follows:

[0046] When in use, the sealing cover 3 is removed, and the operator presses the pressing head 21. Driven by the pressing head 21, the piston 22 moves downward, and the piston head 222 moves downward in the chamber 241. The pump ball 26 remains stationary, and the sealing ball 23 is pushed by the airflow in the chamber 241 to move upward, so that the gas in the bottle body 1 flows from the second channel 212 to the first channel 211 and is discharged; at the same time, the spring 27 is in a compressed state.

[0047] The operator releases the pressing head 21, and under the action of the restoring force of the spring 27, the pressing head 21 moves upward, driving the piston 22 to move upward, and the piston head 222 moves upward in the chamber 241, resulting in low pressure in the chamber 241. The pump ball 26 moves upward under pressure, and the disinfectant in the bottle 1 is sucked into the chamber 241. At the same time, the sealing ball 23 is also adsorbed downward on the slope due to the low pressure in the chamber 241, so that the chamber 241 remains airtight, so that the low pressure generated in the chamber 241 can only inhale the disinfectant but not the outside air.

[0048] Repeat the above process, when the chamber 241 is full of disinfectant, press the pressing head 21 again, drive the piston 22 to move downward, the piston head 222 moves downward in the chamber 241, the pump ball 26 remains stationary, and the sealing ball 23 is pushed by the disinfectant in the chamber 241 to move upward, so that the disinfectant in the bottle body 1 flows from the second hole 212 to the first hole 211 and is discharged, so that the disinfectant can be taken. After use, cover the sealing cover 3.

[0049] The above is a preferred embodiment of the present invention. It should be pointed out that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
