Specific embodiments

[0029] The present application is further described in detail below by specific embodiments in conjunction with the accompanying drawings. Wherein similar elements in different embodiments adopt associated similar element numbers. In the following embodiments, many detailed descriptions are for making the present application better understood. However, those skilled in the art can effortlessly recognize that some features can be omitted in different situations, or can be replaced by other elements, materials, methods. In some cases, some operations related to the present application are not shown or described in the specification, and this is to avoid the core part of the present application being overwhelmed by too much description, and for those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations according to the description in the specification and the general technical knowledge in the art.

[0030] In addition, the features, operations or characteristics described in the specification can be combined in any appropriate manner to form various embodiments, and the operation steps involved in each embodiment can also be replaced or adjusted in order in a manner that is obvious to those skilled in the art. Therefore, the specification and drawings are only for the purpose of clearly describing a certain embodiment, and do not mean that the composition and / or order are necessary.

[0031] The serial numbers of the components in this document, such as "first", "second", etc., are only used to distinguish the objects described and do not have any order or technical meaning. The "connection" and "coupling" mentioned in this application, unless otherwise specified, include direct and indirect connections (couplings).

[0032] In the related art, the efficiency of using a liquid injection needle to fill a liquid storage container is low. Especially when the liquid storage container has a built-in liquid storage material (such as oil storage cotton), the liquid injection needle often needs to be inserted into the bottom of the liquid storage container for filling, and then the liquid injection needle is lifted up layer by layer and filled layer by layer. This filling method requires repeatedly lifting the liquid injection needle, which is inconvenient to operate and has low filling efficiency.

[0033] The present application provides a liquid injection fixture 1, such as Figures 1 to 3 As shown, the liquid injection fixture 1 can be used to inject liquid into the liquid storage container 2. The liquid injection fixture 1 can include a liquid injection tube 11. The shape of the liquid injection tube 11 can be a long strip. The liquid injection tube 11 can be provided with a plurality of liquid outlets 112. Among them, the plurality of liquid outlets 112 can be arranged at intervals along the length direction of the liquid injection tube 11. The liquid outlets 112 penetrate the tube wall of the liquid injection tube 11. The liquid injection tube 11 can be used to be inserted into the liquid storage container 2 to inject liquid into the liquid storage container 2. In one embodiment, the plurality of liquid outlets 112 can be arranged at equal intervals along the length direction.

[0034] In this way, after the injection tube 11 is inserted into the liquid storage container 2, the liquid can flow out from the multiple liquid outlets 112. Since the multiple liquid outlets 112 are provided to increase the liquid outlet area of ​​the injection tube 11, the filling efficiency of the liquid storage container 2 is improved. When the liquid storage container 2 has a liquid storage material built in, the multiple liquid outlets 112 spaced apart along the length direction of the injection tube 11 can be located at different injection positions in the liquid storage container 2, respectively, so that the liquid flowing out of the liquid outlets 112 can simultaneously immerse the liquid storage material from different positions and flow into the liquid storage container 2, so that the filling can be completed at one time, without the need to lift the injection tube 11 layer by layer and fill layer by layer, thereby improving the filling efficiency.

[0035] The liquid storage container 2 may be a liquid storage cup, a liquid storage bottle, or a liquid storage tank. The liquid in the liquid storage container 2 may be an aerosol matrix that can be atomized to generate an aerosol. The present application does not impose any particular restrictions on the specific structure of the liquid storage container 2 or the type of liquid. Figure 2 As shown, when the liquid storage container 2 is a liquid storage bottle, a filling hole 21 may be provided on the liquid storage container 2 so that the liquid injection tube 11 can be inserted into the liquid storage container 2 through the filling hole 21 .

[0036] It should be noted that if Figure 3 As shown, in the drawings, hollow parts such as cavities, openings, and holes are marked with arrows, and other parts are marked with arrows. For example, the marking line shown by the liquid outlet 112 in the figure. In addition, the long strip injection tube 11 can be arranged along the aa axis direction, and the following embodiments will not be repeated.

[0037] In more embodiments, Figures 1 to 3As shown, the multiple liquid outlets 112 can penetrate the tube wall of the liquid injection tube 11 in different directions, and the multiple liquid outlets 112 have different opening directions.

[0038] Thus, the multiple liquid outlets 112 penetrate the tube wall of the liquid injection tube 11 in different directions, so that the multiple liquid outlets 112 can have different opening directions on the tube wall of the liquid injection tube 11, so that the liquid can be injected into the liquid storage container 2 from multiple different directions. When the liquid storage container 2 has a liquid storage material built in, the liquid injected from different directions can quickly penetrate into the liquid storage material, thereby improving the filling efficiency of the liquid storage container 2.

[0039] In one embodiment, if Figure 1 and Figure 3 As shown, the liquid outlet 112 may include a first liquid outlet 1121 and a second liquid outlet 1122. When the injection tube 11 is inserted into the liquid storage container 2, the opening direction of the first liquid outlet 1121 may be toward the middle of the liquid storage container 2, and the opening direction of the second liquid outlet 1122 may be away from the middle of the liquid storage container 2. The first liquid outlet 1121 and the second liquid outlet 1122 may be alternately arranged on the tube wall of the injection tube 11.

[0040] In this way, the liquid can be injected into the liquid storage container 2 from two opposite directions respectively, so as to increase the coverage of the liquid injection and enable the liquid to quickly penetrate into the liquid storage material. In addition, the first liquid outlet 1121 and the second liquid outlet 1122 are alternately arranged on the tube wall of the liquid injection tube 11, which can also make the liquid flowing out from different directions more balanced. Of course, in other embodiments, the opening direction of the first liquid outlet 1121 can also be perpendicular to the opening direction of the second liquid outlet 1122, and the first liquid outlet 1121 and the second liquid outlet 1122 can be alternately arranged with one interval or with multiple intervals. The present application does not impose any special restrictions on the opening direction of the liquid outlet 112 and the specific method of alternating arrangement.

[0041] The injection tube can be one or more. In one embodiment, the injection tube is set to one, such as Figure 3 As shown, a liquid injection port 111 is provided at one end of the liquid injection tube.

[0042] In more embodiments, Figure 1 , Figure 4 and Figure 5As shown, when there are multiple injection tubes 11, the injection fixture 1 may also include an injection head 113, and the injection head 113 is provided with an injection port 111 and a liquid guide channel 1130. The injection port 111 is connected to the outside of the injection fixture 1 and the liquid guide channel; the multiple injection tubes 11 are all connected to the liquid guide channel 1130. When in use, the liquid flows into the injection fixture from the injection port, and passes through the liquid guide channel, injection tube, and liquid outlet of the injection fixture in turn to add liquid to the liquid storage container. Among them, the parts of the multiple injection tubes 11 inserted into the liquid storage container when in use can be parallel to each other to facilitate insertion into the liquid storage container.

[0043] Thus, the efficiency of liquid filling can be further improved by providing a plurality of liquid filling pipes 11. Figure 4 and Figure 5 As shown, the injection tube 11 may have a connected straight section 11a and a curved section 11b, a plurality of liquid outlets 112 are provided on the straight section 11a, and the curved sections 11b of the plurality of injection tubes 11 are all connected and communicated with the injection head 113.

[0044] In this way, the bent section 11b of the liquid injection tube 11 can make multiple liquid injection tubes 11 converge and connect to the liquid injection head 113. When injecting liquid, liquid can be injected into the liquid guide channel 1130 of the liquid injection head 113 through the liquid injection port 111, so that the liquid flows into different liquid injection tubes 11 through the multiple liquid injection ports 111 and flows into the liquid storage container 2 from the multiple liquid outlets 112, thereby further improving the filling efficiency of the liquid storage container 2.

[0045] Among them, Figure 6 As shown, the plurality of injection tubes 11 may be evenly or symmetrically arranged along the circumference of the injection head 113 .

[0046] For example, the injection head 113 can be connected to four injection tubes 11, and the four injection tubes 11 can be symmetrically arranged in an X shape along the circumference of the injection head 113. When the injection tubes 11 are inserted into the liquid storage container 2, the four injection tubes 11 can be located near the four corners of the liquid storage container 2, so that the liquid storage container 2 can be filled from the four corners through the injection fixture 1 of the present application. Of course, in other embodiments, according to the size and shape of the liquid storage container 2, the number of injection tubes 11 can also be set to five, six or more. When the number of injection tubes 11 is an odd number, multiple injection tubes 11 can be evenly arranged along the circumference of the injection head 113. The present application does not impose any special restrictions on the specific number of injection tubes 11.

[0047] In addition, if Figures 1 to 4 As shown, the liquid injection fixture 1 may further include a bracket 12, the bracket 12 may have a accommodating cavity 120 for accommodating the liquid storage container 2, the liquid injection tube 11 is fixedly connected to the bracket 12, the liquid injection port 111 is located outside the accommodating cavity 120, and multiple liquid outlets 112 are located inside the accommodating cavity 120.

[0048] When the liquid injection fixture 1 is provided with a liquid injection head 113, the liquid guide channel 1130 may be located outside the bracket 12, so as to facilitate filling from the liquid injection port 111. When the liquid injection tube 11 is inserted into the liquid storage container 2, the liquid storage container 2 may be located in the accommodating cavity 120, and the bracket 12 may support the liquid injection tube 11, thereby avoiding relative displacement between the liquid injection fixture 1 and the liquid storage container 2. During filling, the liquid may be injected into the liquid storage container 2 through the liquid injection tube 11 through the liquid guide channel 1130.

[0049] Among them, Figure 1 and Figure 7 As shown, the bracket 12 may include a connecting seat 121 and a limiting member 122. The connecting seat 121 is connected to the limiting member 122 and is arranged to form a accommodating cavity 120. The limiting member 122 is used to limit the position of the liquid storage container 2. The injection tube 11 passes through the connecting seat 121, and the injection port 111 is located on the side of the connecting seat 121 away from the accommodating cavity 120.

[0050] When the liquid storage container 2 is located in the accommodating cavity 120, the connecting seat 121 can support the liquid injection tube 11, and the limiting member 122 can limit and fix the position of the liquid storage container 2. Of course, in other embodiments, the bracket 12 can also be set in the form of a ring structure, and the liquid injection tube 11 can be connected to the ring. When filling, the ring can be sleeved on the liquid storage container 2, so that the liquid injection tube 11 can be inserted into the liquid storage container 2. The setting of the ring can also support the liquid injection tube 11, and the present application does not impose any special restrictions on the specific structure of the bracket 12.

[0051] In some embodiments, Figure 1 and Figure 7 As shown, the connecting seat 121 can be provided with a window 1210, and the limiting member 122 can be provided with a hollow area 1220. The window 1210 and the hollow area 1220 can both be connected to the accommodating cavity 120, and the window 1210 and the hollow area 1220 can be used to expose a part of the liquid storage container 2.

[0052] During filling, the progress of filling in the liquid storage container 2 can be observed through the hollow area 1220 on the limiter 122, and whether the liquid storage container 2 is filled in place can be observed through the window 1210 on the connecting seat 121. Figure 2 As shown, when the liquid storage container 2 has a filling nozzle 22. In this way, the window 1210 provided on the connection seat 121 can also be used to accommodate the filling nozzle 22, so that the connection between the liquid injection fixture 1 and the liquid storage container 2 is more reliable. Of course, in other embodiments, the limiter 122 can also be set as a cylindrical structure, so that the liquid storage container 2 can be sleeved and fixed in the cylindrical limiter 122, and the present application does not impose any special restrictions on the specific structure of the limiter 122.

[0053] In more embodiments, Figure 7 As shown, the limiting member 122 may include a first limiting member 1221 and a second limiting member 1222. The first limiting member 1221 and the second limiting member 1222 may be arranged opposite to each other and both connected to the connecting seat 121. The first limiting member 1221 and the second limiting member 1222 may be used to limit the movement of the liquid storage container 2 on both sides.

[0054] Thus, a hollow area 1220 can be formed between the first stopper 1221 and the second stopper 1222. When the liquid storage container 2 is located in the accommodating cavity 120, the first stopper 1221 and the second stopper 1222 can limit the liquid storage container 2, so that the liquid storage container 2 is limited to a position where liquid can be normally injected. The material of the bracket 12 can be rubber, silicone or plastic, and the present application does not impose any special restrictions on the material of the bracket 12.

[0055] In addition, if Figure 1 and Figure 2 As shown, the inner wall shape of the first limiting member 1221 and the second limiting member 1222 can be adapted to the outer wall shape of the liquid storage container 2 .

[0056] In this way, the first stopper 1221 and the second stopper 1222 can cooperate with the liquid storage container 2 to accurately place the liquid storage container at the correct injection position, which also has a foolproof effect to a certain extent. For example, when the liquid storage container 2 is a liquid storage bottle, the inner sidewalls of the first stopper 1221 and the second stopper 1222 can be set to an arc shape that matches the outer contour of the liquid storage bottle. The present application does not impose any special restrictions on the specific shapes of the inner sidewalls of the first stopper 1221 and the second stopper 1222.

[0057] In some embodiments, Figure 3 As shown, the injection tube 11 may be provided with a closed puncture portion 114 at one end away from the injection port 111 . The puncture portion 114 may be designed in a sharp shape, such as a cone, and is used to pierce the liquid storage container.

[0058] During filling, since the puncture portion 114 is in a closed state, the liquid cannot flow out through the puncture portion 114, but can only flow out from the liquid outlet 112, thereby ensuring that the liquid flows into the liquid storage container 2 through multiple liquid outlets 112. At the same time, it is avoided that during the process of piercing the liquid storage container with liquid storage material, the liquid storage material enters the liquid injection tube 11, thereby causing the problem of clogging the liquid outlet 112. In addition, the setting of the puncture portion 114 can also make the liquid injection tube 11 easily inserted into the liquid storage container 2, so as to improve the efficiency of filling.

[0059] The above specific examples are used to illustrate the present invention, which are only used to help understand the present invention and are not intended to limit the present invention. For those skilled in the art of the present invention, some simple deductions, deformations or substitutions can be made based on the idea of ​​the present invention.
