Description

Technical Field

[0001] This invention belongs to the technical field of kitchen and bathroom products, and relates to a bottle cap connection structure for a deodorizing and antibacterial machine. Background Technology

[0002] The deodorizing and antibacterial machine is a device for processing kitchen waste. It includes a bottle and a cap connected to the bottle. The cap contains components such as a liquid pump, which can draw out the deodorizing and antibacterial liquid in the bottle through a straw extending from the bottle and spray it onto the waste to be processed, so as to inhibit the growth of bacteria in the waste. During use, the connection structure must ensure the connection and locking effect between the cap and the bottle. When the deodorizing and antibacterial liquid in the bottle is exhausted, the cap needs to be unlocked and removed to replenish it.

[0003] Patent application number CN202510061917.0 discloses a locking and unloading device for a filter bottle. The filter bottle includes a bottle body and a cap. The cap is detachably fixed at the bottle opening at the top of the bottle body. A filter element is located in the space between the bottle body and the cap. The filter bottle is detachably fixed in the filter bottle cavity of a suitable filter machine body. The cap includes a base and a handle. The base includes a base and a cover. The base has a recessed mounting cavity. Unlocking grooves are provided on both sides of the central shaft. There is a locking tongue in the unlocking groove. There is a push shaft on the locking tongue. An elastic element is fixed between the inner end of the locking tongue and the unlocking groove to keep it in an outward popping tendency. The corresponding base has a base unlocking hole. When using this product, the user only needs to turn the handle on the top of the bottle. During the rotation of the handle, the arc-shaped guide hole drives the push shaft to move along the transverse slide, thereby moving the locking tongue inward. The locking tongue moves away from the fixed part on the machine body, such as the lock hole, passes through the base unlock hole and the cap unlock hole, and then retracts into the unlock groove. Then, the bottle body is pulled out from the filter bottle cavity of the filter body by the handle. After replacing the new filter element, the bottle body is pushed back into the filter bottle cavity. With the force applied by the elastic element, the locking tongue passes through the base unlock hole and the cap unlock hole and is fixed to the fixed part on the machine body, such as the lock hole, thereby achieving the locked state.

[0004] The above structure achieves a locking connection by engaging the two outwardly extending locking tongues on the base with the locking holes on the body. However, there are still shortcomings: during the unlocking process, the user needs to first rotate the handle to unlock and keep it rotating before pulling the bottle out of the body. If only the handle is pulled out, it is easy to damage the connection of the handle, which is only connected by the central shaft. If the cap is pulled out after unlocking, it often requires two hands to operate, which is not convenient. Summary of the Invention

[0005] In view of the above-mentioned problems in the existing technology, the present invention provides a bottle cap connection structure for a deodorizing and antibacterial machine. The technical problem to be solved by the present invention is that the existing bottle cap connection structure is not convenient to use.

[0006] The objective of this invention can be achieved through the following technical solutions:

[0007] A bottle cap connection structure for a deodorizing and antibacterial machine, the antibacterial machine including a bottle body and a cap shell, the cap shell being cylindrical, the bottle cap connection structure including two locking members and two positioning holes located on the outer periphery of the cap shell, the locking members being positioned and embedded in the positioning holes, characterized in that the cap shell has a cylindrical sleeve with an open bottom, the outer periphery of the sleeve having an insertion hole at a position opposite to the positioning hole, the sleeve being sleeved on the upper end of the bottle body, the locking members being annular plates, the inner edge of the locking members having an inwardly protruding locking tongue, the two locking members stacked abutting each other and both sleeved on the outer periphery of the sleeve, a return spring arranged along the direction of the positioning hole between the two locking members, the two ends of the return spring acting on the inner edge of the locking member and the outer edge of the other locking member, the locking tongue passing through the insertion hole and being axially positioned on the upper end of the bottle body, the locking tongue retracting into the insertion hole when the two locking members move horizontally towards each other.

[0008] The bottle body is used to store the deodorizing and antibacterial liquid. The cap shell, part of the bottle cap, serves as a protective structure for the cap components and provides a structural framework for their installation. Locking elements are used to lock the cap shell to the bottle body via a snap-fit ​​mechanism. Positioning holes on the cap shell allow the locking elements to be inserted for proper positioning. A return spring ensures the locking elements self-reset, guaranteeing the locking effect. A cylindrical sleeve with an upward arch is provided on the bottom surface of the cap shell's inner cavity. Insertion holes are located on the outer circumference of the sleeve opposite the positioning holes. Two ring-shaped locking elements are also provided, with inwardly extending locking tongues on the inner edges of each element. Both locking elements are fitted with... The locking tongue is positioned on the outer periphery of the sleeve, passing through the insertion hole and the upper end of the bottle. The specific method of axial positioning of the locking tongue and the bottle can refer to existing technology. This allows the locking element in the positioning hole to be pressed directly from the outside to the inside, which can drive the two locking elements to move towards each other. The positioning hole and the insertion hole can provide vertical positioning for the locking elements. With the two locking elements abutting against each other, their horizontal movement is stable, thereby allowing the locking tongue on the inner edge of the locking element to retract into the insertion hole to unlock the cap and the bottle. At the same time, the hand can be inserted into the positioning hole while applying force, thereby separating the cap and the bottle, making the separation operation safer and more convenient.

[0009] In the bottle cap connection structure of the deodorizing and antibacterial machine described above, an inwardly extending guide strip is integrally connected to the locking member at a position radially opposite to the locking tongue. Each locking member is vertically positioned between another locking member and the guide strip on the other locking member. By providing a guide strip extending opposite to the locking tongue on the locking member, it is beneficial to make the two locking members nested together to form a vertical positioning while providing further guidance for relative horizontal sliding. Moreover, the two locking members nested together form a limiting and guiding effect on each other. With the help of the sleeve, sufficient constraint effect can be generated on the two locking members, saving the need for constraint structure settings for the locking members inside the cap shell. The overall number of parts is more streamlined, making the assembly process more convenient.

[0010] In the bottle cap connection structure of the above-mentioned deodorizing and antibacterial machine, the outer periphery of the sleeve has a guide rib plate that is arranged in the direction of the positioning hole and is in the shape of a vertical plate. The vertical side of the guide rib plate has a limiting notch. The inner edge of the locking member near the locking tongue also has a strip-shaped clearance notch. The guide rib plate is located in the clearance notch, and the locking member is vertically positioned in the limiting notch. When the two locking members move towards each other, the locking member can disengage from the limiting notch. Because of the reset spring, the two locking components, when pre-assembled, tend to move backwards. This results in a large horizontal dimension after assembly in its natural state, making direct insertion into the cover housing impossible. When inserting the two locking components into the cover housing cavity, force must first be applied to compress them, causing them to move towards each other and reducing their overall size. After compressing the two locking components, the assembler can then insert them from above into the cover housing and place them around the outer circumference of the sleeve. At this point, the assembler's fingers can fit between the locking components and the inner wall of the cover housing, but it is difficult to move them further downwards. During this process, the upper part of the guide rib plate is embedded in the clearance notch, preventing the two locking components from moving backwards through the outer vertical edge of the guide rib plate. Even when the assembler releases their grip, the locking components will not protrude outwards. The inner wall of the cover abuts against the pressure point, causing wear, and increases the overlapping area of ​​the inner holes of the two locking parts, preventing direct contact and friction with the sleeve surface. Simultaneously, the guide ribs provide circumferential positioning for the locking parts, ensuring accurate orientation. The assembler simply presses the locking parts downwards, allowing them to move along the vertical edge of the guide ribs with less resistance. The locking parts then spring into the limiting notch, completing the assembly. The inner wall of the limiting notch provides further constraint from above, stabilizing the locking parts' position. The clicking sound produced during this process alerts the assembler to the correct installation, making the assembly process more convenient. Furthermore, the locking parts are not interfered with by the guide ribs during subsequent horizontal movement, ensuring smooth operation.

[0011] In the bottle cap connection structure of the aforementioned deodorizing and antibacterial machine, the upper edge of the guide rib is inclined downwards from the inside out. This allows the guide rib to partially embed into the clearance notch and calibrate its circumferential position even if the pressure applied by the assembler is insufficient after pressing the two locking parts. Then, as the assembler applies downward force, the inclined upper edge converts some of the downward force into auxiliary pressing force, causing the two locking parts to move towards each other. This facilitates the simultaneous pressing and engagement of the guide rib and the clearance notch, making the assembly process labor-saving and convenient.

[0012] In the bottle cap connection structure of the deodorizing and antibacterial machine described above, the inner edge of each locking member has two opposing and parallel guide surfaces, which are arranged along the opening direction of the positioning hole. Another locking member is partially embedded between the two guide surfaces and can reciprocate along these guide surfaces. This helps to ensure the directional stability of the two locking members during their relative and opposite movements, thereby ensuring the accuracy of the unlocking operation.

[0013] In the bottle cap connection structure of the deodorizing and antibacterial machine described above, each locking member has several locking tongues, which are arranged at intervals around the circumference of the locking member. The number of insertion holes on the outer circumference of the sleeve is the same as the number of locking tongues. This multi-point locking tongue positioning with the bottle body facilitates positioning stability.

[0014] In the bottle cap connection structure of the deodorizing and antibacterial machine described above, the inner cavity bottom surface of the sleeve has a guide groove arranged along the opening direction of the positioning hole, and the outer edge of the locking member has a vertically protruding pressing plate in the shape of a vertical plate. The lower part of the pressing plate is slidably embedded in the guide groove, and the guide strip is connected to the inner side of the pressing plate. In this way, after the locking member is assembled, the mounting plate can slide along the guide groove, ensuring that the circumferential position of the locking member is stable and reliable, and the movement direction is more accurate. The guide strip set on the pressing plate facilitates the formation of a vertical gap between it and the locking member body, allowing another locking member to be embedded and combined.

[0015] In the bottle cap connection structure of the deodorizing and antibacterial machine described above, the guide groove communicates with the positioning hole, and the inner wall of the guide groove smoothly transitions with the inner wall of the positioning hole. The pressing plate is embedded in the guide hole. Thus, during assembly, simply push down and move the locking member to the bottom, allowing the mounting plate to embed itself in the guide groove and contact the bottom surface. Guided by the inner wall of the guide groove, the mounting plate can be stably embedded in the positioning hole when the two locking members move back and forth, avoiding situations where the mounting plate cannot be accurately embedded in the positioning hole, making assembly more convenient.

[0016] In the bottle cap connection structure of the deodorizing and antibacterial machine described above, the locking tongues on both locking components are located at the same height. This helps to ensure the positioning stability of each locking tongue relative to the upper end of the bottle.

[0017] In the bottle cap connection structure of the deodorizing and antibacterial machine described above, each locking component has two parallel spaced guide strips arranged along the direction of the positioning hole. The inner side of each guide strip has a limiting protrusion. The outer edge of the locking component, corresponding to the locking tongue, has a vertically protruding, plate-shaped abutment. One side of the abutment abuts against the outer periphery of the sleeve, and the other side is opposite to the position between the two guide strips. When the abutment moves along the two guide strips to abut against the limiting protrusion, the protruding end of the locking tongue retracts into the insertion hole. Thus, when the user presses the locking component to unlock, the abutment moves between the two guide strips and contacts the limiting protrusion. This creates significant resistance, alerting the operator to the unlocking process and preventing the user from continuing to apply force to the return spring due to uncertainty about the unlocking status, which would reduce the lifespan of the return spring.

[0018] In the bottle cap connection structure of the deodorizing and antibacterial machine described above, the side of the limiting protrusion opposite to the abutment is rounded. When the abutment abuts against the other side of the limiting protrusion, the locking tongue disengages from the insertion hole, and the locking member disengages from the positioning hole. Thus, when the locking member needs to be disassembled for maintenance, a large squeezing force can be applied to move the two locking members towards each other. When the abutment moves along the two guide strips to abut against the limiting protrusion, it can push the two guide strips open and deform under the guidance of the rounded corners, and the abutment is engaged with the other side of the limiting protrusion to form a positioning. At this time, the two locking members lock the return spring under the action of the abutment and the limiting protrusion. The two locking members can function as a structurally stable component, and the locking members are not constrained by the positioning hole and insertion hole, allowing them to be easily removed from the cap, making disassembly and assembly more convenient.

[0019] Compared with the prior art, the advantages of the present invention are as follows:

[0020] This deodorizing and antibacterial machine allows operators to directly press the locking element in the positioning hole from the outside in, causing the two locking elements to move towards each other. This retracts the locking tongue on the inner edge of the locking element into the insertion hole, unlocking the cap from the bottle. Furthermore, applying force by hand can also separate the cap from the bottle, making the operation safer and more convenient. At the same time, the two locking elements are nested together to form a limit and guide, saving the need for a constraint structure for the locking elements inside the cap, making the assembly process more convenient.

[0035] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0036] like Figure 1 As shown, this deodorizing and antibacterial machine includes a bottle body 1 and a cap shell 2. The cap shell 2 is connected to the upper end of the bottle body 1. The outer periphery of the cap shell 2 has a positioning hole 21, and the locking member 4 is embedded in the positioning hole 21.

[0037] like Figure 2-5As shown, the cap shell 2 is cylindrical, and a reset spring 3 is provided inside the cap shell 2. The cap connection structure includes two horizontally arranged plate-shaped locking members 4. There are two positioning holes 21, which are spaced apart around the outer periphery of the cap shell 2. The reset spring 3 is arranged along the setting direction of the positioning holes 21. The locking members 4 are all positioned and embedded in the positioning holes 21. The lower end of the cap shell 2 is closed, and the bottom surface of the inner cavity has an upwardly arched cylindrical sleeve 22. The outer periphery of the sleeve 22 has a insertion hole 23 at a position opposite to the positioning hole 21 in the radial direction. The middle of the two locking members 4 is vertically and horizontally connected in a ring shape. The two locking members 4 are sleeved on the outer periphery of the sleeve 22. The inner edge of the locking member 4 has an inwardly protruding locking tongue 41, and the locking member 4 and the locking tongue are connected. 41 are radially oppositely connected with inwardly extending guide bars 42, which are arranged along the direction of the positioning hole 21. Two locking members 4 are stacked on top of each other, and each locking member 4 is vertically positioned between the other locking member 4 and the guide bar 42 on the other locking member 4. The two ends of the reset spring 3 act on the inner edge of the locking member 4 and the outer edge of the other locking member 4, respectively. The outer periphery of the sleeve 22 has a guide rib plate 24 arranged in a vertical plate shape along the opening direction of the positioning hole 21. The vertical side of the guide rib plate 24 has a limiting notch 241. The inner edge of the locking member 4 near the locking tongue 41 also has a strip-shaped clearance notch 43, and the guide rib plate 24 is located in the clearance notch 43. The inner edge of each locking member 4 has two opposite and parallel guide surfaces 44, which are arranged along the opening direction of the positioning hole 21. The other locking member 4 is partially embedded between the two guide surfaces 44 and can reciprocate along the guide surface 44. The upper edge of the guide rib plate 24 is inclined downward from the inside out. Each locking member 4 has two locking tongues 41, arranged circumferentially around the locking member 4. The sleeve 22 has four insertion holes 23 on its outer periphery, and the locking tongues 41 on both locking members 4 are located at the same height. The inner cavity bottom surface of the sleeve 22 has a guide groove 25 arranged along the opening direction of the positioning hole 21. The outer edge of the locking member 4 has a vertically protruding, plate-shaped pressing plate 45, the lower part of which is slidably embedded in the guide groove 25. A guide strip 42 is connected to the inner side of the pressing plate 45, and each locking member 4 has two parallel, spaced guide strips 42. The guide groove 25 communicates with the positioning hole 21, and the inner wall of the guide groove 25 smoothly transitions with the inner wall of the positioning hole 21. The pressing plate 45 is embedded in the guide hole. The outer edge of the locking member 4 has a vertically protruding, plate-shaped abutment part 46 corresponding to the locking tongue 41.

[0038] like Figure 6-8 As shown, the cap 2 is connected to the upper end of the bottle body 1 through the locking member 4, and the sleeve 22 is fitted on the upper outer periphery of the bottle body 1. The upper outer periphery of the bottle body 1 has an annular shoulder 11. The protruding end of the locking tongue 41 passes through the insertion hole 23 and its upper side is limited and abutted against the annular shoulder 11 to achieve axial positioning. The locking member 4 is vertically positioned in the limiting notch 241.

[0039] like Figure 9 , Figure 10 As shown, the inner side of the guide bar 42 has a limiting protrusion 421. One side of the abutting part 46 abuts against the outer periphery of the sleeve 22, and the other side of the abutting part 46 is opposite to the position between the two guide bars 42. When the abutting part 46 moves along the two guide bars 42 to abut against the limiting protrusion 421, the protruding end of the locking tongue 41 retracts into the insertion hole 23.

[0040] like Figure 11-13 As shown, the side of the limiting protrusion 421 opposite to the abutment 46 is rounded. When the abutment 46 abuts against the other side of the limiting protrusion 421, the locking tongue 41 disengages from the insertion hole 23, and the locking member 4 disengages from the positioning hole 21 and the locking member 4 disengages from the limiting notch 241.

[0041] When the user needs to remove the cover 2, they can squeeze the locking piece 4 located in the positioning hole 21 with their fingers. By overcoming the force of the reset spring 3, the two locking pieces 4 move towards each other, and the locking tongue 41 on the locking piece 4 can be disengaged from below the annular shoulder 11 to release the axial positioning between the cover 2 and the bottle body 1. Then, the user can directly separate the cover 2 from the bottle body 1 by applying upward force, which is convenient to use.

[0042] When it is necessary to disassemble or assemble the locking member 4, a large force can be applied to the locking member 4 in the positioning hole 21 to move the two locking members 4 toward each other, so that the abutment part 46 and the other side of the limiting protrusion 421 form a limiting abutment. At this time, the reset spring 3 is locked along the axial direction. The user can take out the two locking members 4 locked together from the top of the cover 2. The removal process is convenient. When putting the two locking members 4 back into the cover 2, press the two locking members 4 together and put them on the outside of the sleeve 22 at the same time. Finally, press down until the locking member 4 springs into the positioning hole 21 to complete the assembly.

[0043] The specific embodiments described herein are merely illustrative of the spirit of the invention. Those skilled in the art to which this invention pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of the invention or exceeding the scope defined by the appended claims.
