Description

Technical Field

[0001] This utility model belongs to the field of aromatherapy technology, specifically relating to an electrically controlled valve structure for an aromatherapy diffuser. Background Technology

[0002] As the economy develops and people's quality of life improves, all kinds of aromatherapy products have entered people's lives. These products not only bring a comfortable olfactory experience, but are also often combined with interior decoration, personal taste and the art of living.

[0003] Existing fragrance products use technologies such as combustion, heating, atomization, or increasing surface area to aid evaporation to release fragrance. Among these, combustion is less commonly used due to the safety hazards posed by open flames; the latter three methods are more prevalent. However, heating and atomization require more complex components. For example, heating requires heating elements such as heating wires to heat the fragrance product, while atomization requires a combination of atomizing plates and liquid guides, or an ultrasonic atomizer combined with liquid fragrance. Both of these methods result in complex internal structures for the fragrance products. Using cotton swabs, cotton pads, or rattan to increase surface area for evaporation results in uncontrollable fragrance release speed and poor fragrance dispersion.

[0004] Existing fragrance diffusers mostly use single-fragrance release or achieve multiple fragrance selection through mechanical switching (as shown in application number CN202210381522.5), which suffers from problems such as complex structure, low switching accuracy, and easy damage. Furthermore, they often require separate airflow channels and fans for different fragrances, meaning one airflow channel and one fan correspond to one fragrance (as shown in application number CN202221296925.1), resulting in a complex overall structure, relatively large size, and increased cost. Some electric fragrance diffusers use solenoid valves to control airflow, but these typically employ linear motion valve cores, resulting in complex structures and large space requirements.

[0005] Secondly, some existing aromatherapy diffusers that use replaceable fragrance consumables often require the fragrance carrier inside the consumable to be used in conjunction with a car air conditioner. This results in an opening for gas flow on both sides of the consumable, as shown in the existing published document CN220125180U, which describes an aromatherapy jar and an aromatherapy diffuser with the same. In this case, there is no sealing structure at the air inlet and outlet of the diffuser's container. Therefore, even when not in use, this leads to unnecessary evaporation and waste of the fragrance carrier inside the jar, affecting its lifespan. Utility Model Content

[0006] The purpose of this utility model is to overcome the existing technical defects and provide an electrically controlled valve structure for an aroma diffuser. By using a flap and a drive device to form an electrically controlled valve for sealing and opening a single receiving slot, it is possible to switch between different fragrances. It also features a simple structure, high reliability and low cost.

[0007] In the first aspect, in order to solve the above-mentioned technical problems, the present invention provides an electrically controlled valve structure for an aroma diffuser. The aroma diffuser includes a main unit having at least one receiving slot and at least one aroma diffuser jar placed in the receiving slot in a one-to-one correspondence. The upper end of the receiving slot is open, and each receiving slot has a flap for sealing and located above the aroma diffuser jar at its upper end. The main unit is also provided with at least one drive device for driving the flap to rotate and open in a one-to-one correspondence.

[0008] Furthermore, at least one end of the flap is provided with a magnet, and the driving device is an electromagnetic coil that cooperates with the magnet.

[0009] Furthermore, a magnet is provided at each of the two ends of the flap, and the driving device includes two electromagnetic coils that correspond to the magnets one by one.

[0010] Furthermore, the host is also provided with at least one air inlet that is connected to the receiving slot and located above the flap.

[0011] Furthermore, the main unit includes a housing consisting of an upper shell and a lower shell, and a fan located at the upper end of the upper shell. The drive device is located on the outside of the lower shell. At least one receiving slot is formed inside the lower shell. The middle parts of both ends of the flap are rotatably mounted on the lower shell via a rotating shaft. A first partition is vertically arranged in the receiving slot and located between the flap and the aromatherapy jar. A second partition is provided on the inner side of the upper shell at the position corresponding to each receiving slot, located above the flap. The upper end of the second partition is bent and extended to provide a closing part for closing part of the receiving slot opening. An air outlet is formed between the side of the opening away from the closing part and the second partition. After the flap is rotated open, it is located between the first partition and the second partition to divide the upper end of the receiving slot into a first air flow chamber and a second air flow chamber. The air inlet is connected to the first air flow chamber, and the air inlet of the fan is connected to the second air flow chamber through the air outlet.

[0012] Furthermore, an elastic element is provided between the flap and the first or second partition to restore the flap to a horizontal state.

[0013] Furthermore, the elastic element is a torsion spring, with one end fixed to the second partition and the other end fixed to the flap.

[0014] Furthermore, the front and rear walls of the receiving groove are recessed with guide grooves for inserting the second partition plate; the left and right walls of the receiving groove are respectively provided with a first stop plate and a second stop plate that abut against the surface of the flip plate, and the first stop plate and the second stop plate are respectively located on the lower and upper sides of the flip plate.

[0015] Furthermore, the aromatherapy jar includes a hollow jar body, an aroma-generating carrier suspended inside the jar body, and a lid that is closed at one end of the jar body. The jar body has interconnected airflow ports on its left and right sides, so that the two airflow ports are respectively located below the first airflow cavity and the second airflow cavity; the lid is located outside the main unit.

[0016] Furthermore, the main unit also includes a housing and a main board disposed within the housing. The housing and the fan are disposed within the housing, and the main board is fixed to the rear side of the housing. The main board is electrically connected to the drive device and the fan respectively. The front end of the housing is provided with at least one insertion port for each aromatherapy jar to be inserted into the receiving slot. The cover is located outside the housing. The housing is provided with an air inlet at the position corresponding to each of the air inlets, and the housing is also provided with an air outlet communicating with the air outlet of the fan.

[0017] This utility model has the following beneficial effects: In this invention, a flap is installed at the upper opening of each receiving tank to seal it. Each flap is driven to open by a corresponding driving device to achieve the purpose of dispersing fragrance outward. That is, the flap in the receiving tank and the driving device work together to control the opening and closing of the fragrance dispersing channel of a single receiving tank, thereby achieving the purpose of switching between different fragrances. It has the characteristics of simple structure, high reliability and low cost. The flap rotary valve occupies little space and is conducive to multi-cavity layout. Moreover, the driving device uses an electromagnetic coil, which works with a magnet to drive the flap to move quickly, and the fragrance switching is almost without delay.

[0018] Secondly, the air inlet and air outlet of the container are both located above the flap. When the flap is in a horizontal state and the container is closed, the space at the bottom of the container used to hold the aromatherapy jar is in a relatively closed state, reducing unnecessary evaporation waste from the aromatherapy jar.

[0019] In addition, a single fan can be used to output fragrance from all the aroma diffusers in the compartments, meaning that multiple aroma diffusers can share a single fragrance outlet, which makes the overall structure of the machine relatively simple and reduces product costs.

[0020] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and will become apparent from the description or may be learned by practice of the invention. Attached Figure Description

Detailed Implementation

[0022] To better understand the technical content of this utility model, the following will further introduce and explain this utility model in conjunction with the accompanying drawings and specific embodiments. It should be noted that if there are descriptions such as "first" and "second" in the text, they are used to distinguish different components, etc., and do not represent the order of priority, nor do they limit "first" and "second" to be different types.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Example like Figures 1 to 14 As shown in the figure, the aroma diffuser in this embodiment includes a main unit 1 with three receiving slots 10 and three aroma diffuser jars 2 placed one-to-one in the receiving slots. One end of the aroma diffuser jar 2 is located outside the main unit for easy insertion and removal. The upper end of the receiving slot 10 is open, and each receiving slot 10 has a flap 3 rotatably mounted on its upper end for sealing and located above the aroma diffuser jar 2. That is, the flap 3 is in a horizontal state in the normal state to seal the upper end of the receiving slot 10. The main unit 1 also has multiple drive devices 4 for driving the flap 3 to rotate and open one-to-one. That is, when it is necessary to open a certain flap jar 2, the drive device 4 can be used to open the flap jar 2. When the aroma diffuser inside the container is to diffuse fragrance, the corresponding drive device 4 simply needs to be activated to rotate and open the flap. After the flap 3 is rotated and opened, it is generally in a vertical position. By setting a flap at the upper opening of each container to seal it, and each flap being driven to open by a corresponding drive device, the purpose of dispersing fragrance outward is achieved. That is, the flaps in the container and the drive device work together to control the opening and closing of the fragrance dispersing channel of a single container, thereby achieving the purpose of switching between different fragrances. It has the characteristics of simple structure, high reliability and low cost.

[0025] In one embodiment, such as Figures 3 to 14 As shown, the host 1 includes a housing 11 and a shell, a fan 12 and a motherboard 13 disposed inside the housing 11. The shell is composed of an upper shell 14 and a lower shell 15 that are fitted together. The fan 12 is installed in the middle of the upper shell 14, the drive device 4 is disposed on the outside of the lower shell 15, and the motherboard 13 is electrically connected to the fan 12 and the drive device 4 respectively.

[0026] Specifically, such as Figures 3 to 14As shown, the lower shell 15 has three receiving slots 10, with the upper end of each slot 10 being open. The middle portions of both ends of the flap 3 are rotatably mounted on the lower shell 15 via rotating shafts 31, meaning the flap 3 rotates up and down around its center. When in a vertical position, it is positioned exactly in the middle of the width of the receiving slot 10. A first partition 151 is vertically positioned within the receiving slot 10 and located between the flap 3 and the aromatherapy jar 2. On the inner side of the upper shell 14, a second partition 141 protrudes downwards at each corresponding position in the receiving slot 10 and is positioned above the flap 3. When the flap 3 is rotated open to a vertical position, it is positioned between the first partition 151 and the second partition 141, meaning the first partition 151 and the second partition 141 are positioned exactly at... On both sides of the vertically positioned flap, without affecting the up-and-down rotation of the flap 3, the second partition 141, the flap, and the first partition 151 are sequentially arranged from top to bottom to form an isolation section, which divides the upper end of the receiving groove 10 into a first air flow cavity 101 and a second air flow cavity 102. The lower shell 15 is also provided with three air inlets 152 that are connected one-to-one to the first air flow cavity 101 and located above the flap, so that the air inlet and air outlet (i.e. the opening at the upper end) of the receiving groove are both located above the flap. When the flap is in a horizontal position and closes the receiving groove, the space in the lower end of the receiving groove used to hold the aromatherapy jar is in a relatively closed state, reducing unnecessary evaporation waste of the aromatherapy jar.

[0027] In one embodiment, such as Figures 3 to 14 As shown, in order to improve the fragrance diffusion effect and efficiency, and to allow the air to flow through the aromatherapy jar below after entering the receiving tank, the upper end of the second partition 141 is bent and extended to provide a sealing part 142 for sealing part of the opening of the receiving tank 10. That is, part of the opening at the upper end of the receiving tank 10 is blocked by the second partition and the sealing part, so that the air cannot flow directly upward and enter the fan. It must first flow downward along the first air flow cavity 101 and flow through the aromatherapy jar, and then flow upward along the second air flow cavity 102. An air outlet is formed between the side of the opening at the upper end of the receiving tank away from the sealing part 142 and the second partition 141. The air inlet of the fan 12 is connected to the second air flow cavity 102 through the air outlet. The air outlets of the three receiving tanks are all connected to the air inlet of the fan 12, so that the fragrant air is finally absorbed by the fan and output to the outside.

[0028] In one embodiment, such as Figures 4 to 6As shown, the aroma diffuser 2 includes a hollow body 21, a fragrance carrier 22 suspended inside the body 21, and a cover 23 fitted onto one end of the body 21. The cover 23 is located outside the main unit 1, and the cover 23 facilitates the insertion and removal of the aroma diffuser. The left and right sides of the body 21 are provided with interconnected air flow ports 24, so that the two air flow ports 24 are respectively located below the first air flow cavity 101 and the second air flow cavity 102, so that the air flowing up and down will enter the aroma diffuser from one side of the air flow port 24 and come into contact with the fragrance carrier, and then flow out from the other side of the air flow port 24.

[0029] In one embodiment, as shown in the figure, the closing part 142 is a horizontal plate extending horizontally to the inner wall of the upper shell or a right-angled plate extending horizontally and vertically in sequence, with the vertical part of the right-angled plate abutting against the upper end surface of the lower shell 15.

[0030] In one embodiment, such as Figures 12 to 13 As shown, a magnet 32 ​​is embedded at each end of the flip plate 3, and the two magnets 32 at each end are respectively located on both sides of the rotating shaft 31, forming an interlaced design. The driving device 4 includes two electromagnetic coils that correspond to the magnets 32 one by one. That is, three electromagnetic coils that correspond to the magnets 32 are provided on the front and rear sides of the lower shell 15. It can be seen that six electromagnetic coils are provided for the three flip plates. When the electromagnetic coils are energized, the magnetic field generated attracts or repels the magnets, thereby driving the flip plates to rotate.

[0031] Specifically, when the flip plate is in a horizontal state, the position of the electromagnetic coil can correspond to or be offset from the inside and outside of the magnet. When they are aligned, the magnetic field generated by the electromagnetic coil after it is energized repels the magnet, thereby driving the flip plate to rotate. When they are offset, the magnetic field generated by the electromagnetic coil after it is energized attracts the magnet, thereby driving the flip plate to rotate.

[0032] Specifically, such as Figure 11 As shown, mounting posts 153 for mounting and fixing electromagnetic coils are provided on both the front and rear sides of the lower shell 15.

[0033] In another different embodiment, a magnet may be provided only at one end of the flap, and no magnet may be provided at the other end, so that the number of electromagnetic coils provided on the outside of the lower shell is three.

[0034] In one embodiment, such as Figures 3 to 14 As shown, an elastic element 5 is provided between the flap 3 and the first partition 151 or the second partition 141 to restore the flap 3 to a horizontal state. That is, when the electromagnetic coil is not working, the elastic element 5 applies a rebound force to the flap to restore it to the horizontal state of the seal.

[0035] In one embodiment, the elastic element 5 is a torsion spring. One end of the torsion spring is fixed to the second partition 141, and the other end is fixed to the flap. The structure of using a torsion spring to realize the flap rotation and return to its original position is a conventional technical means in the present, and will not be described in detail here.

[0036] In one embodiment, such as Figures 3 to 11 As shown, the upper ends of both the front and rear walls of the receiving groove 10 are recessed with guide grooves 103 for the insertion of the second partition 141, which guides and limits the insertion of the upper shell; the left and right walls of the receiving groove 10 are respectively provided with a first stop plate 104 and a second stop plate 105 that abut against the surface of the flap 3, and the first stop plate 104 and the second stop plate 105 are respectively located on the lower and upper sides of the flap 3, thereby limiting the rotation of the flap 3, ensuring that the flap 3 is in a sealed horizontal state after rotating back to its original position under the action of the elastic member 3, and improving the sealing of its lower space.

[0037] In one embodiment, such as Figures 1 to 7 As shown, the front end of the outer shell 10 is provided with three insertion ports 107 for the aroma diffuser 2 to be inserted into the receiving slot 10 one by one, and the cover 23 is located outside the outer shell 10; the outer shell 10 is provided with an air inlet 108 at the position corresponding to each air inlet 152, and the outer shell 10 is also provided with an air outlet 109 that communicates with the air outlet of the fan 12.

[0038] In one embodiment, the fragrance carrier is preferably a ceramic fragrance body that absorbs perfume.

[0039] In other embodiments, the fragrance carrier is preferably a long, rod-shaped structure.

[0040] In other embodiments, a soft rubber sealing ring (not shown in the figure) may be added to the four edges of the flap to improve its airtightness when it is closed for sealing.

[0041] In other embodiments, the number of insertion ports, receiving slots, and aromatherapy jars can also be set to 2, 4, or more.

[0042] The technical solutions provided by the embodiments of this utility model have been described in detail above. Specific examples have been used to illustrate the principles and implementation methods of the embodiments of this utility model. The description of the above embodiments is only for helping to understand the principles of the embodiments of this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the embodiments of this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
