[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present utility model clearer, the technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0029] In a laboratory, it is often necessary to use a bottle washer to perform operations such as preparing reagents, transferring samples, or cleaning. During use, it is usually necessary to squeeze the bottle body of the bottle washer to make the liquid in the bottle body flow out from the nozzle of the bottle washer. However, in the related art, the flow rate of the bottle washer is usually controlled by the squeezing force, that is, the flow rate can only be indirectly controlled by controlling the squeezing force. This adjustment method has a relatively high operation difficulty and a low control accuracy.

[0030] To solve or improve the problem that in the related art, the flow rate of the bottle washer is usually controlled by the squeezing force, with a relatively high operation difficulty and a low control accuracy, an embodiment of the present utility model provides a bottle washer.

[0031] The following combines Figures 1 to 5 , to describe the bottle washer provided in the embodiments of the present utility model.

[0032] Specifically, the bottle washer includes a bottle body 1, an inner nozzle 2, and an outer nozzle 3.

[0033] Among them, the bottle body 1 is used to hold liquid.

[0034] The first end of the inner nozzle 2 is connected to the bottle body 1, and the bottle body 1 can supply liquid to the inner nozzle 2. The second end of the inner nozzle 2 is provided with at least three elastic pieces 201 distributed circumferentially, that is, at least three elastic pieces 201 are sequentially distributed along the circumference of the inner nozzle 2. Along the direction from the first end to the second end of the inner nozzle 2, the two side edges of the elastic piece 201 gradually approach each other, that is, along the direction from the first end to the second end of the inner nozzle 2, the width of the elastic piece 201 gradually decreases. For example, the elastic piece 201 can be integrally in a triangular structure.

[0035] The outer nozzle 3 is set as a conical sleeve, and the outer nozzle 3 is threadedly connected to the inner nozzle 2. Specifically, the outer nozzle 3 is threadedly connected to the second end of the inner nozzle 2, wherein the outer nozzle 3 is sleeved on the outside of the second end of the inner nozzle 2, that is, the outer nozzle 3 is provided with an internal thread, and the inner nozzle 2 is provided with an external thread.

[0036] The elastic pieces 201 at the second end of the inner nozzle 2 are all arranged inside the outer nozzle 3, and the outer nozzle 3 is used to squeeze the elastic pieces 201 and make the elastic pieces 201 approach each other. That is, during the process of screwing the outer nozzle 3, the conical inner surface of the outer nozzle 3 abuts against the elastic piece 201, so as to achieve the effect of squeezing the elastic piece 201.

[0037] In this embodiment, the inner nozzle 2 is connected to the bottle body 1 so that the bottle body 1 can supply liquid to the inner nozzle 2. By providing at least three elastic pieces 201 on the inner nozzle 2, and the outer nozzle 3 set as a conical sleeve is sleeved on the outside of the elastic piece 201 and threadedly connected to the inner nozzle 2, when screwing the outer nozzle 3, the relative position relationship between the outer nozzle 3 and the inner nozzle 2 in the axial direction can be adjusted, so as to adjust the extrusion degree of the conical inner surface of the outer nozzle 3 on the elastic piece 201. By adjusting the extrusion degree of the outer nozzle 3 on the elastic piece 201, the approaching degree between the elastic pieces 201 can be adjusted, that is, the size of the gap between the elastic pieces 201 is adjusted, so as to achieve the effect of changing the flow cross-sectional area of the inner nozzle 2, that is, changing the opening size of the inner nozzle 2, and further the flow rate can be controlled.

[0038] With such a setting, the bottle washer provided in this embodiment can change the extrusion degree of the outer nozzle 3 on the elastic piece 201 by screwing the outer nozzle 3, so as to adjust the size of the gap between the elastic pieces 201, thereby changing the opening size of the inner nozzle 2, achieving the effect of controlling the flow rate. Compared with the method of controlling the flow rate solely by the extrusion force, the control is more accurate and the operation difficulty is lower.

[0039] For example, in the case where a large amount of liquid needs to be discharged, the outer nozzle 3 can be screwed in the direction away from the inner nozzle 2, so as to reduce the degree of extrusion of the outer nozzle 3 on the elastic sheet 201, thereby increasing the gap between the elastic sheets 201 to increase the flow rate. In the case where precise liquid discharge is required, such as in the process of titration or preparation, the outer nozzle 3 can be screwed in the direction close to the inner nozzle 2, so as to increase the degree of extrusion of the outer nozzle 3 on the elastic sheet 201, thereby reducing the gap between the elastic sheets 201 to reduce the flow rate and facilitating precise control of the flow rate.

[0040] Optionally, the inner nozzle 2 includes a connecting pipe section for connecting to the bottle body 1. Along the direction of the liquid flowing out of the bottle body 1, the elastic sheet 201 is connected to the end of the connecting pipe section away from the bottle body 1. The outer nozzle 3 is connected to the connecting pipe section. Optionally, the elastic sheet 201 and the connecting pipe section can be integrally formed. Optionally, the elastic sheet 201 is made of a plastic sheet or a steel sheet.

[0041] Reference Figures 1 - 4 As shown, in some embodiments provided by the present utility model, at least a part of the bottle body 1 is provided with an elastic structure. For example, a part of the bottle body 1 is made of a plastic structure, or the whole is made of a plastic structure.

[0042] The washing bottle further includes a first one-way valve 4 and a second one-way valve 5. The bottle body 1 is provided with a liquid inlet. The first one-way valve 4 is connected to the liquid inlet, and the conducting direction of the first one-way valve 4 is from the outside to the inside of the bottle body 1. The liquid inlet can be connected to a liquid replenishing container. The second one-way valve 5 is connected between the inner nozzle 2 and the bottle body 1, that is, the inner nozzle 2 is connected to the bottle body 1 through the second one-way valve 5. The conducting direction of the second one-way valve 5 is from the bottle body 1 to the inner nozzle 2.

[0043] In this embodiment, by setting at least a part of the bottle body 1 as an elastic structure, the liquid in the bottle body 1 can be discharged by squeezing the bottle body 1, making the use of the washing bottle more convenient. During the process of squeezing the bottle body 1, the first one-way valve 4 is closed and the second one-way valve 5 is opened, and the liquid in the bottle body 1 can enter the inner nozzle 2 and be sprayed out through the outer nozzle 3 through the second one-way valve 5. After the squeezing force on the bottle body 1 disappears, during the process of the bottle body 1 recovering its deformation, a negative pressure is generated inside the bottle body 1. At this time, the first one-way valve 4 is opened and the second one-way valve 5 is closed, and the bottle body 1 can absorb liquid from the liquid replenishing container through the liquid inlet and the second one-way valve 5, so as to replenish the liquid in the bottle body 1.

[0044] With such a setting, in the washing bottle according to the embodiment of the present utility model, by setting at least a part of the bottle body 1 as an elastic structure and providing the first one-way valve 4 and the second one-way valve 5, after squeezing the bottle body 1 to discharge the liquid, the bottle body 1 can automatically suck in liquid for replenishment during the process of recovering its deformation. On the one hand, it is not necessary to manually add liquid to the bottle body 1, saving time and effort. On the other hand, the washing bottle can be continuously used, and the operation is more convenient.

[0045] In some embodiments provided by the present utility model, the washing bottle further includes a liquid replenishing tube 6. The liquid replenishing tube 6 is connected to the liquid inlet. Figure 1 and Figure 3 As shown, the liquid infusion tube 6 is connected to the liquid inlet through the first one-way valve 4, wherein the inlet end of the first one-way valve 4 is connected to the liquid infusion tube 6, and the outlet end of the first one-way valve 4 is connected to the liquid inlet.

[0046] In this embodiment, the liquid infusion tube 6 is provided so that the bottle body 1 is connected to the liquid infusion container through the liquid infusion tube 6, so that the relative positions of the liquid infusion container and the bottle body 1 can be more flexible.

[0047] Furthermore, the infusion tube 6 is configured as a hose. By configuring the infusion tube 6 as a hose, the adaptability of the infusion tube 6 is improved, so that the operator can move and operate the bottle body 1 more easily.

[0048] In some embodiments provided by the utility model, the washing bottle further comprises a liquid replenishing container, the liquid replenishing container is used to contain liquid, and the end of the liquid replenishing tube 6 away from the bottle body 1 extends into the liquid replenishing container. Optionally, the liquid replenishing container can be a liquid replenishing box or a liquid replenishing tank.

[0049] In this embodiment, a liquid replenishing container is provided, and the liquid replenishing tube 6 extends into the liquid replenishing container, so that the liquid replenishing container can replenish liquid into the bottle body 1 during the process of the bottle body 1 recovering its deformation.

[0050] In some embodiments provided by the utility model, the washing bottle further comprises a flow control valve 7, which is connected between the inner mouth 2 and the bottle body 1. In the embodiment provided with the second one-way valve 5, the inner mouth 2 is connected to the bottle body 1 through the flow control valve 7 and the second one-way valve 5.

[0051] In this embodiment, by providing the flow control valve 7, on the one hand, the flow rate of the bottle body 1 entering the inner mouth 2 can be controlled by the flow control valve 7, so as to achieve the effect of controlling the flow rate of the bottle washing, that is, the flow control valve 7 can work together with the matching structure between the inner mouth 2 and the outer mouth 3 to adjust the flow rate of the bottle washing. On the other hand, the flow control valve 7 can also disconnect the inner mouth 2 from the bottle body 1, that is, the bottle body 1 can be closed by the flow control valve 7. For example, when the bottle body 1 is not in use, the bottle body 1 can be closed by the flow control valve 7 to prevent the liquid in the bottle body 1 from flowing out from the inner mouth 2 and the outer mouth 3 when the bottle body 1 is squeezed, causing waste or pollution.

[0052] Optionally, the flow control valve 7 may be a ball valve or a stop valve.

[0053] In some embodiments provided by the present utility model, the flow control valve 7 has a manual handle 8 for adjusting the valve opening.

In this way, the structure of the flow control valve 7 is simple, facilitating the operator to manually adjust the flow control valve 7 according to actual needs.

[0055] In some embodiments provided by the present utility model, the bottle washer further includes a scale disk 9, which is connected to the valve body of the flow control valve 7 and is used to indicate the position of the manual handle 8.

[0056] In this embodiment, by providing the scale disk 9 to visually indicate the position of the manual handle 8, the scale disk 9 can provide a visual reference point, facilitating the operator to more accurately control the opening degree of the valve port of the flow control valve 7.

[0057] In some embodiments provided by the present utility model, the bottle washer further includes a liquid outlet pipe 10. The inner nozzle 2 is connected to the bottle body 1 through the liquid outlet pipe 10. The end of the liquid outlet pipe 10 away from the inner nozzle 2 extends into the bottle body 1 and is close to the bottom of the bottle body 1.

[0058] In this embodiment, the inner nozzle 2 is connected to the bottle body 1 through the liquid outlet pipe 10, and the liquid outlet pipe 10 is close to the bottom of the bottle body 1, which can ensure that the liquid in the bottle body 1 is emptied to the maximum extent, reducing residues and improving the usage efficiency.

The bottle cap 11 is detachably disposed on the bottle mouth of the bottle body 1, and the liquid outlet pipe 10 passes through the bottle cap 11 and extends into the bottle body 1. For example, the liquid outlet pipe 10 is hermetically connected to the bottle cap 11.

[0060] In this embodiment, by providing the bottle cap 11, the bottle body 1 can be opened. For example, liquid can be added to the bottle body 1 in the initial state, or it is convenient to clean the inside of the bottle body 1.
