Description

Technical Field

[0001] This utility model relates to the field of suction device technology, specifically a portable negative pressure suction device. Background Technology

[0002] A negative pressure suction device is a tool that creates a negative pressure state in its suction head through a certain method, so that the material outside the suction head is squeezed towards the suction head, thereby achieving the "suction" effect.

[0003] The negative pressure suction device consists of a pressure regulator, a collection bottle, and flexible tubing. The collection bottle has two tubing interfaces, one connected to the negative pressure terminal and the other connected to the working chamber. When the negative pressure terminal is connected, a negative air pressure is generated inside the collection bottle, which guides waste (such as blood, sputum, etc.) into the collection bottle through the other tubing.

[0004] Existing negative pressure suction devices have the following disadvantages when in use:

[0005] 1. Existing negative pressure suction devices have separate components, making them inconvenient to carry and use;

[0006] 2. At the same time, the existing negative pressure suction device cannot detect the liquid level in the collection bottle and cannot effectively prevent the backflow of liquid in the collection bottle;

[0007] 3. Existing negative pressure suction devices cannot guide waste to containers other than collection bottles, which limits their use.

[0008] This invention addresses these issues by proposing a portable negative pressure suction device, which aims to solve the aforementioned problems. The device is easy to carry, can monitor the liquid level in the container in real time to prevent backflow of contaminants, and can be connected to other containers, thus broadening its application range. Utility Model Content

[0009] In view of the above-mentioned shortcomings in the prior art, the present invention provides a portable negative pressure suction device.

[0010] To achieve the aforementioned objectives, the technical solution adopted by this utility model is as follows:

[0011] A portable negative pressure suction device includes a housing, a controller, and a battery, wherein the housing houses the controller and the battery.

[0012] The housing includes a fixed frame and a pull-out frame, the pull-out frame being slidably connected to the fixed frame, the front of the fixed frame having a touch screen, and the inner surface of the fixed frame having a controller and a battery;

[0013] A negative pressure box is provided at the upper inner side of the pull-out frame, and a holding container is provided below the negative pressure box. The negative pressure box is connected to the holding container through a connecting component, and the negative pressure box is detachably connected to the holding container through the connecting component.

[0014] The negative pressure box and the container are equipped with a liquid level detection component, which detects the liquid level in the container.

[0015] A negative pressure pump is provided on the inner surface of the pull-out frame. The negative pressure pump is connected to the negative pressure box through a connecting pipe. An electric opening valve is provided at the connection between the connecting pipe and the negative pressure box. An external pipe is provided on the side of the negative pressure box and is connected to it. A solenoid valve is provided at the connection between the external pipe and the negative pressure box. The external pipe protrudes from the pull-out frame. A feed pipe is provided on the upper surface of the negative pressure box and is connected to it. The feed pipe protrudes from the upper surface of the pull-out frame.

[0016] As an improvement, the connecting component includes a connecting pipe one, a connecting pipe two, and a connecting sleeve. The connecting pipe one is located on the lower end face of the negative pressure box. A solenoid valve two is provided at the connection between the connecting pipe one and the negative pressure box. The connecting pipe two is located on the upper end face of the container. A connecting sleeve is threadedly connected to the lower end of the connecting pipe one, and the lower end of the connecting sleeve is threadedly connected to the upper end of the connecting pipe two.

[0017] As an improvement, the container is detachably connected to the lower end face of the pull-out frame, and a limiting frame is provided on the inner surface of the lower end face of the pull-out frame to limit the position of the lower end of the container.

[0018] As an improvement, the liquid level detection component includes an optical liquid level sensor and a light-transmitting plate. The optical liquid level sensor is disposed on the lower end face of the negative pressure box, and the light-transmitting plate is disposed on the upper end face of the container. The positions of the optical liquid level sensor and the light-transmitting plate correspond.

[0019] As an improvement, both the outer pipe and the feed pipe are provided with stepped connectors at the ends away from the negative pressure box.

[0020] As an improvement, both the outer pipe and the feed pipe are made of corrugated pipe.

[0021] Compared to traditional technologies, the advantages of this utility model are:

[0022] 1. All components are fixedly installed in the fixed frame and pull-out frame that make up the shell. The width of the entire shell is 5cm, the thickness is 5cm and the height is 15cm, making it easy to carry and use.

[0023] 2. The liquid level sensor can detect the liquid level in the container. When the liquid level in the container reaches the set value, the negative pressure pump stops operating to prevent the liquid in the container from overflowing and backflowing.

[0024] 3. By controlling the on / off state of solenoid valve one and solenoid valve two, the on / off state of the external pipe is controlled, so that the liquid attracted by the negative pressure suction device can be flexibly connected to external containers, making its application range wider.

[0032] To make the content of this utility model easier to understand, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of this utility model.

[0033] Example 1

[0034] Combined with appendix Figure 1-4 The housing contains a controller and a battery. The housing includes a fixed frame 1 and a pull-out frame 2. The pull-out frame 2 is slidably connected to the fixed frame 1. The front of the fixed frame 1 is provided with a touch screen 3. The inner surface of the fixed frame 1 is provided with a controller and a battery.

[0035] The upper inner side of the pull-out frame 2 is provided with a negative pressure box 4, and a container 5 is provided below the negative pressure box 4. The negative pressure box 4 is connected to the container 5 through a connecting component.

[0036] The negative pressure box 4 and the container 5 are equipped with liquid level detection components, which detect the liquid level in the container 5.

[0037] The inner surface of the pull-out frame 2 is provided with a negative pressure pump 6. The negative pressure pump 6 is connected to the negative pressure box 4 through a connecting pipe 7. An electric opening valve 8 is provided at the connection between the connecting pipe 7 and the negative pressure box 4. The side of the negative pressure box 4 is provided with an external pipe 9 connected to it. A solenoid valve 10 is provided at the connection between the external pipe 9 and the negative pressure box 4. The external pipe 9 protrudes from the pull-out frame 2. The upper end face of the negative pressure box 4 is provided with a feed pipe 11 connected to it. The feed pipe 11 protrudes from the upper end face of the pull-out frame 2. A solenoid valve 25 is provided at the connection between the connecting pipe 12 and the negative pressure box 4.

[0038] The liquid level detection component includes an optical liquid level sensor 17 and a light-transmitting plate 18. The optical liquid level sensor 17 is disposed on the lower end face of the negative pressure box 4, and the light-transmitting plate 18 is disposed on the upper end face of the container 5. The positions of the optical liquid level sensor 17 and the light-transmitting plate 18 are corresponding.

[0039] In use, the feed pipe 11 is connected to the working chamber, and the negative pressure pump 6 is controlled by the touch screen 3. The negative pressure pump 6 is connected to the negative pressure box 4 through the connecting pipe 7. Negative pressure is generated in the negative pressure box 4, and the liquid in the working chamber is drawn into the negative pressure box 4 through the feed pipe 11.

[0040] When the container 5 is used to store liquid, solenoid valve 10 is closed and solenoid valve 2 is open. At this time, the liquid entering the negative pressure box 4 will not be discharged through the external pipe 9, but will enter the container 5 through the connecting component. When the liquid enters the container 5, the optical liquid level sensor 17 on the lower end face of the negative pressure box 4 detects the liquid level in the container 5 in real time through the light-transmitting plate 18 on the upper end face of the container 5. When the liquid level in the container 5 reaches the set value, the negative pressure pump 6 stops operating to prevent the liquid in the container 5 from overflowing and backflowing.

[0041] When other containers are used to store the liquid, solenoid valve 10 is opened and solenoid valve 2 is closed. At this time, the liquid entering the negative pressure box 4 will not enter the holding container 5 through the connecting parts, but will be discharged through the external pipe 9. The external pipe 9 is connected to other containers to draw the liquid to the designated location.

[0042] Combined with appendix Figure 1-4 Both the outer pipe 9 and the feed pipe 11 are provided with stepped connectors 19 at the ends away from the negative pressure box 4, and both the outer pipe 9 and the feed pipe 11 are made of corrugated pipe.

[0043] The stepped connector 19 on the external pipe 9 and the feed pipe 11 facilitates the connection between the working chamber and the external container. At the same time, the external pipe 9 and the feed pipe 11 are made of corrugated pipe, which makes it easy to adjust their length according to the actual use.

[0044] Example 2

[0045] Combined with appendix Figure 1-4 The connecting component includes a first connecting pipe 12, a second connecting pipe 13, and a connecting sleeve 14. The first connecting pipe 12 is located on the lower end face of the negative pressure box 4. A second solenoid valve 15 is provided at the connection between the first connecting pipe 12 and the negative pressure box 4. The second connecting pipe 13 is located on the upper end face of the container 5. The lower end of the first connecting pipe 12 is threadedly connected to the connecting sleeve 14, and the lower end of the connecting sleeve 14 is threadedly connected to the upper end of the second connecting pipe 13.

[0046] The container 5 is detachably connected to the lower end face of the pull-out frame 2. The inner surface of the lower end face of the pull-out frame 2 is provided with a limiting frame 16, which limits the position of the lower end of the container 5.

[0047] Based on Embodiment 1, when the liquid in the container 5 is full, the container 5 needs to be removed and poured out. At this time, rotate the connecting sleeve 14, and the connecting sleeve 14 moves upward on the connecting pipe 12. The connecting sleeve 14 separates from the connecting pipe 2 13, and the container 5 can be removed from the limiting frame 16.

[0048] Example 3

[0049] Based on Embodiments 1 and 2, the battery inside the casing can be charged simply by plugging it in. The touchscreen 3 displays the negative pressure value, with a negative pressure adjustment range of -10Kpa to 80Kpa. The negative pressure pump 6 generates less than 40 decibels of noise during operation.

[0050] The above description is only a preferred embodiment of this utility model patent and is not intended to limit this utility model patent. Any modifications, equivalent substitutions and improvements made within the spirit and principles of this utility model patent should be included within the protection scope of this utility model patent.
