Description

Technical Field

[0001] This application claims the priority of a patent application with the application number 2022213683656 and the invention title "Valve Assembly", which was filed with the China National Intellectual Property Administration on June 2, 2022.

[0002] This application relates to the technical field of valve assemblies, specifically to valve assemblies.

Background Art

[0003] Currently, a conventional valve assembly includes a bottle body and a solenoid valve. The bottle body is provided with a bottle mouth, and the solenoid valve is provided at the bottle mouth. In the prior art, the solenoid valve and the bottle body are connected by a screw at the bottle mouth. The weight of the solenoid valve is concentrated entirely at the bottle mouth. Moreover, most of the material of the bottle body is plastic, and this material has low load-bearing capacity and durability. Therefore, after the solenoid valve and the bottle body have been loosened and tightened multiple times, a screw slipping phenomenon appears in the screw structure between the solenoid valve and the bottle body, resulting in looseness between the two, and even detachment, which further affects the normal use of the device.

Summary of the Invention

[0004] This application provides a valve assembly for solving the problem of low connection strength between a solenoid valve and a bottle body in the prior art.

[0005] This application provides a valve assembly including a bottle body having a bottle mouth, provided with a fixing part, the fixing part and the bottle mouth being located on the same side and provided at an interval from each other, a locking groove being provided on the side wall of the fixing part, and a solenoid valve provided at the bottle mouth, having a connection port and a valve port communicating with each other, the connection port and the bottle mouth being in communication, and a locking protrusion being further provided on the side part of the solenoid valve, the locking protrusion being locked and engaged with the locking groove so as to limit the axial displacement of the solenoid valve with respect to the bottle body.

[0006] In the application of the technical aspects of this application, the bottle body is provided with a fixing portion, and a locking groove is provided on the side wall of the fixing portion, and a locking projection is provided on the side of the solenoid valve, and the solenoid valve and the bottle body can be fixedly connected by the connection and engagement of the locking groove and the locking projection. With this design, after the solenoid valve and the bottle body are attached, the force acting to restrict each other by the locking groove and the locking projection effectively reduces the situation in which force is received at the bottle opening, thereby making the force distribution of the entire bottle body more uniform and ensuring stability after connection between the solenoid valve and the bottle body, preventing looseness and even detachment due to multiple loosening and tightening of the two, and at the same time making the use of the device easier.

[0007] Furthermore, the locking groove is located on one side of the fixed part adjacent to the bottle opening, and has an opening at one end. The locking groove extends along the circumferential direction of the fixed part, and the locking projection enters the locking groove from the opening and engages with the locking groove. With this design, the locking projection is moved into the locking groove by a rotational method, and the above operation is simple and convenient, reducing the difficulty of installing the device and improving the installation efficiency of the device.

[0008] Furthermore, the locking groove includes sequentially arranged avoidance segments and position-restricting segments along the circumferential direction, with an opening provided at one end of the avoidance segment away from the position-restricting segment, and the bottom of the position-restricting segment being lower than the bottom of the avoidance segment, thereby restricting the axial displacement of the locking projection and restricting the rotation of the locking projection within the locking groove through engagement between the locking projection and the position-restricting segment. With this design, during the installation process of the device, the solenoid valve can rotate to the avoidance segment, then move along the axis to the position-restricting segment and engage with the position-restricting segment, thereby improving the stability after connection between the locking projection and the locking groove, which is advantageous for improving the connection stability between the solenoid valve and the bottle body.

[0009] Furthermore, multiple fixing parts are provided, which surround the outer circumference of the bottle opening. Each fixing part has one locking groove, and the multiple locking grooves are arranged sequentially along the rotational direction of the locking projection. The solenoid valve has multiple locking projections, and there is a one-to-one correspondence between the locking projections and the locking grooves. By providing multiple locking grooves and multiple locking projections, the connection between the solenoid valve and the bottle body is made stronger, and at the same time, the overall structural strength after the connection between the two can be improved.

[0010] Furthermore, the valve assembly further includes an elastic preload member provided between the solenoid valve and the bottle body, which can provide an axial elastic force to the solenoid valve. With this design, the elasticity of the elastic preload member allows the locking projection and locking groove of the solenoid valve to be tightly connected, preventing the locking projection from falling out of the locking groove due to vibration of the device, and further ensuring the stability of the connection between the locking projection and the locking groove.

[0011] Furthermore, the bottle body is provided with a housing groove that surrounds the outer circumference of the bottle opening. One end of the elastic preload member is located within the housing groove, and the other end of the elastic preload member abuts against the solenoid valve. This design allows for precise positioning of the elastic preload member, ensures accuracy when installing the elastic preload member, and the above structure allows for rational use of the space within the bottle body, reducing the space required for mounting the device.

[0012] Furthermore, the solenoid valve includes a magnetic induction frame with locking protrusions on its exterior, a valve body inserted into the magnetic induction frame having a connecting end and a free end facing each other, with a connecting port provided at the connecting end and a valve port provided at the free end, and the connecting end of the valve body being screwed into the bottle opening, and a coil assembly fixed to the magnetic induction frame and surrounding the outer circumference of the valve body. Fixing the valve body and coil assembly to the magnetic induction frame allows the coil assembly and valve body to be connected to the bottle body, improving the overall structural stability of the solenoid valve, further improving the connection stability between the solenoid valve and the bottle body, and further, the above-described installation makes the structure of the essential oil valve more compact and reduces its volume, thereby enabling miniaturization of the device.

[0013] Furthermore, the valve body includes a fixed iron core, one end of which is inserted into the bottle opening and screwed into the bottle opening, and which has a connection port; a housing to which the other end of the fixed iron core is connected, which has a chamber and a valve port, the connection port and the chamber are in communication, and the valve port is provided at the bottom and communicates with the chamber; and a movable iron core that is movably provided within the chamber and used to open or close the valve port. By providing the above structure, the valve body can open or close the valve port with the movable iron core, thereby controlling the flow rate of essential oil inside the bottle and reducing situations in which essential oil is wasted during the use process.

[0014] Furthermore, the axial length of the avoidance segment is greater than or equal to the thickness of the locking projection. This design ensures sufficient space for the locking projection, making it easier for the projection to rotate into the avoidance segment, and further facilitating the installation of the solenoid valve, thereby improving the installation efficiency of the solenoid valve.

[0015] Furthermore, a reinforcing structure is provided between the fixing part and the bottle body. This design improves the structural strength of the fixing part through the reinforcing structure, ensuring stability during long-term use of the device and also having the advantage of extending the device's service life.

[Modes for carrying out the invention]

[0019] The following will clearly and completely describe the technical solutions in the embodiments of the present application by referring to the drawings in the embodiments of the present application. It is clear that the described embodiments are only some embodiments of the present application, not all embodiments. Hereinafter, the description of at least one exemplary embodiment is actually only illustrative and does not impose any limitation on the present application and its application or use. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative efforts shall fall within the protection scope of the present application.

[0020] As shown in FIGS. 1 and 6, the present application provides a valve assembly including a bottle body 10 and a solenoid valve 20. Here, the bottle body 10 has a bottle mouth 11, and a fixing part 12 is provided on the bottle body 10. The fixing part 12 and the bottle mouth 11 are located on the same side of the bottle body 10 and are provided at an interval. A locking groove is provided on the side wall of the fixing part 12. The solenoid valve 20 is provided at the bottle mouth 11 and has a connection port 21 and a valve port 22 that communicate with each other. The connection port 21 and the bottle mouth 11 are in communication. A locking protrusion 23 is further provided on the side part of the solenoid valve 20. The locking protrusion 23 is locked and engaged with the locking groove so as to limit the displacement of the solenoid valve 20 in the axial direction with respect to the bottle body 10.

[0021] When the technical solution of the present application is applied, a fixing part 12 is provided on the bottle body 10, and a locking groove is provided on the side wall of the fixing part 12. A locking protrusion 23 is provided on the side part of the solenoid valve 20. The solenoid valve 20 and the bottle body 10 can be fixedly connected by the connection and engagement of the locking groove and the locking protrusion 23. Designed in this way, after the solenoid valve 20 and the bottle body 10 are installed, the locking groove and the locking protrusion 23 effectively reduce the situation of receiving force at the bottle mouth 11 due to the acting force that restricts each other. Thereby, the overall force reception of the bottle body 10 is made more uniform, and the stability after the connection between the solenoid valve 20 and the bottle body 10 can be ensured, preventing phenomena such as looseness, rattling, and even dropping caused by multiple tightening and loosening of both, and at the same time, the use of the device is also facilitated.

[0022] As shown in FIGS. 2 to 4, the locking groove is located on one side close to the bottle mouth 11 of the fixing part 12, and one end of the locking groove has an opening. The locking groove extends along the circumferential direction of the fixing part 12. The locking protrusion 23 enters the locking groove from the opening and is locked and engaged with the locking groove. Designed in this way, the locking protrusion 23 is moved into the locking groove by a rotational method. The above operation is simple and convenient in method, can reduce the difficulty of installing the device, and can improve the installation efficiency of the device. Of course, in other embodiments of the present application, the locking protrusion 23 may directly move into the locking groove and be locked and engaged with the locking groove. The specific installation situation may also be selected according to the use environment of the device, which is beneficial to expanding the application range of the device.

[0023] Specifically, the locking groove includes an avoidance segment 13 and a position limiting segment 14 provided sequentially along the circumferential direction. An opening is provided at one end of the avoidance segment 13 away from the position limiting segment 14. The bottom of the position limiting segment 14 is lower than the bottom of the avoidance segment 13. By engaging the locking protrusion 23 with the position limiting segment 14, the displacement of the locking protrusion 23 in the axial direction can be limited, and the rotation of the locking protrusion 23 in the locking groove can be limited. Designed in this way, during the installation process of the device, the solenoid valve 20 can rotate to the avoidance segment 13 and then continue to rotate into the position limiting segment 14 and be limit-engaged with the position limiting segment 14, thereby improving the stability after the connection between the locking protrusion 23 and the locking groove, which is beneficial to improving the connection stability between the solenoid valve 20 and the bottle body 10.

[0024] As shown in Figures 5 and 7, in the embodiment of this application, the end of the locking projection 23 that enters the locking groove is arc-shaped, and both the avoidance segment 13 and the position limiting segment 14 are provided as rectangular structures. The above-described structure is simple and easy to manufacture, satisfies the connection and restriction requirements between the solenoid valve 20 and the bottle body 10, and at the same time reduces the manufacturing cost of the device. Of course, the locking projection 23 may be provided as a square or trapezoidal structure, and the avoidance segment 13 and the position limiting segment 14 only need to be provided as a mechanism that restricts each other with respect to the locking projection 23 and satisfies the restriction requirements of the device.

[0025] Furthermore, multiple fixing parts 12 are provided, and these fixing parts 12 surround the outer circumference of the bottle opening 11. Each fixing part 12 is provided with one locking groove, and the multiple locking grooves are sequentially provided along the rotational direction of the locking projection 23. The solenoid valve 20 has multiple locking projections 23, and there is a one-to-one correspondence between the locking projections 23 and the locking grooves. By providing multiple locking grooves and multiple locking projections 23, the connection between the solenoid valve 20 and the bottle body 10 can be made stronger, and at the same time, the overall structural strength after the connection between the two can be improved.

[0026] In this embodiment, there are two fixing parts 12, which are symmetrically arranged along both sides of the bottle opening 11, and there are two locking projections 23, which are symmetrically arranged along both sides of the solenoid valve 20. This design makes the overall layout of the device more rational, while also allowing the weight of the solenoid valve 20 to be distributed more uniformly across the fixing parts 12, resulting in more uniform force distribution on the bottle body 10, further reducing the force received at the bottle opening 11, and ensuring stability after connection between the solenoid valve 20 and the bottle body 10.

[0027] Specifically, the valve assembly further includes an elastic preload member 30, which is provided between the solenoid valve 20 and the bottle body 10, and can provide an axial elastic force to the solenoid valve 20. With this design, the elasticity of the elastic preload member 30 allows the locking projection 23 and the locking groove on the solenoid valve 20 to be tightly connected, preventing the locking projection 23 from falling out of the locking groove due to vibration of the device, and further ensuring the stability of the connection between the locking projection 23 and the locking groove.

[0028] In this embodiment of the present application, the elastic preload member 30 is specifically a spring, and the above-described structure is simple and easy to process, can satisfy the pressing and limiting requirements of the locking projection 23, is easy to install, facilitates attachment and detachment of the device, and improves the efficiency of attachment and detachment of the device. Of course, the elastic preload member 30 may be provided as an elastic piece as long as it can satisfy the requirement of preload limiting the locking projection 23.

[0029] Furthermore, the bottle body 10 is provided with a housing groove 15, which surrounds the outer circumference of the bottle opening 11. One end of the elastic preload member 30 is located within the housing groove 15, and the other end of the elastic preload member 30 abuts against the solenoid valve 20. This design allows for the positioning of the elastic preload member 30, ensures accuracy when installing the elastic preload member 30, and the above structure rationally utilizes the space of the bottle body 10, reducing the space required for mounting the device. Moreover, by providing the above structure, it is possible to increase the number of spring turns by a certain number, ensure that the spring has sufficient elastic force, and furthermore, satisfy the restriction requirements on the spring's locking projection 23.

[0030] Specifically, the solenoid valve 20 includes a magnetic induction frame 24, a valve body, and a coil assembly 25. A locking projection 23 is provided on the outside of the guide magnetic frame 24, the valve body is inserted into the magnetic induction frame 24, the valve body has a connecting end and a free end facing each other, a connecting port 21 is provided at the connecting end, and a valve port 22 is provided at the free end, the connecting end of the valve body is screwed into the bottle opening 11, the coil assembly 25 is fixed to the magnetic induction frame 24, and the coil assembly 25 surrounds the outer circumference of the valve body. Fixing the valve body and coil assembly 25 to the magnetic induction frame 24 allows the coil assembly 25 and the valve body to be connected to the bottle body 10, improving the overall structural stability of the solenoid valve 20, further improving the connection stability between the solenoid valve 20 and the bottle body 10, and moreover, the above installation makes the structure of the essential oil valve more compact and reduces its volume, thereby enabling miniaturization of the device.

[0031] Furthermore, the valve body includes a fixed core 26, a housing 27, and a movable core 28. Here, one end of the fixed core 26 is inserted into the bottle opening 11 and screwed into the bottle opening 11, and the fixed core 26 is provided with a connection port 21. The other end of the fixed core 26 is connected to the housing 27, and the housing 27 has a chamber and a valve port 22, the connection port 21 and the chamber are in communication, the valve port 22 is provided at the bottom of the housing 27 and is in communication with the chamber, and the movable core 28 is movably provided within the chamber and is used to open or close the valve port 22. By providing the above structure, the valve body can open or close the valve port 22 by the movable core 28, thereby controlling the flow rate of essential oil in the bottle body 10 and reducing situations in which essential oil is wasted during the use process.

[0032] In this embodiment, during the installation process, the fixed iron core 26 and the bottle opening 11 are first tightened with screws, thereby fixing the valve body and the bottle body 10 in place. Then, the elastic preload member 30 is placed into the housing groove 15, and finally, the magnetic induction frame 24 of the assembled solenoid valve is rotated into the position limiting segment 14 inside the locking groove, thereby completing the overall assembly of the device.

[0033] Specifically, the axial length of the avoidance segment 13 is L1, and L1 is greater than or equal to the thickness of the locking projection 23. If L1 is less than the thickness of the locking projection 23, there will not be enough space for the locking projection 23 to move into the avoidance segment 13, and the mounting requirements of the device cannot be met. Therefore, by making L1 greater than or equal to the thickness of the locking projection 23, sufficient space can be secured for the locking projection 23, making it easier for the locking projection 23 to rotate into the avoidance segment 13, and further, making it easier to mount the solenoid valve 20 and improving the mounting efficiency of the solenoid valve 20.

[0034] Here, the axial length of the position limiting segment 14 is L2, and L1 ≥ 0.1 mm. If L2 is less than 0.1 mm, after the locking projection 23 and the position limiting segment 14 are connected, the position limiting segment 14 cannot ensure that the entire locking projection 23 is located within the position limiting segment 14. When the device shakes, the locking projection 23 is likely to separate from the position limiting segment 14, causing the solenoid valve 20 and the bottle body 10 to rattle, and the stability of the connection between the solenoid valve 20 and the bottle body 10 cannot be ensured. Therefore, setting L1 ≥ 0.1 mm effectively prevents the locking projection 23 from falling out of the position limiting segment 14, and ensures the stability of the device during operation.

[0035] Furthermore, the width of the position limiting segment 14 is L3, and the width of the locking projection 23 is L4, so L3 ≥ L4. If L3 is smaller than L4, there will not be enough space for the locking projection 23 to move from the avoidance segment 13 into the position limiting segment 14, and the mounting requirements of the device cannot be met. Therefore, setting L3 ≥ L4 ensures sufficient space for the locking projection 23, making it easy for the locking projection 23 to move into the avoidance segment 13. At the same time, the locking projection 23 can automatically engage into the position limiting segment 14 under the action of the elastic preloading member 30, thereby realizing the self-locking function of the device.

[0036] Furthermore, a reinforcing structure 40 is provided between the fixing part 12 and the bottle body 10. This design improves the structural strength of the fixing part 12 with the reinforcing structure 40, ensuring stability during long-term use of the device and also having the advantage of extending the device's service life.

[0037] In the application of the technical aspects of this application, the bottle body 10 is provided with a fixing portion 12, and a locking groove is provided on the side wall of the fixing portion 12, and a locking projection 23 is provided on the side of the solenoid valve 20, and the solenoid valve 20 and the bottle body 10 can be fixedly connected by the connection and engagement of the locking groove and the locking projection 23. With this design, after the solenoid valve 20 and the bottle body 10 are attached, the force acting to restrict each other by the locking groove and the locking projection 23 effectively reduces the force received at the bottle opening 11, thereby making the overall force distribution of the bottle body 10 more uniform and ensuring stability after connection between the solenoid valve 20 and the bottle body 10, preventing looseness and even detachment due to multiple loosening and tightening of the two, and at the same time making the use of the device easier. In addition, a reinforcing structure 40 is provided between the fixing portion 12 and the bottle body 10, which improves the structural strength of the fixing portion 12 and ensures stability during long-term use of the device.
