Description

Technical Field

[0001] The present invention relates to the technical field of aroma sprayers, in particular to a aroma sprayer. Background Art

[0002] In daily life and various public places, fragrance dispensers are widely used as devices for distributing fragrance and improving the odor of the environment. To achieve the spray function, traditional fragrance dispensers usually have a cylinder and a base. The cylinder is equipped with a liquid storage tank for storing the fragrance liquid, a fragrance dispensing assembly connected to the liquid storage tank, and a control module that controls the opening and closing of the fragrance dispensing assembly to perform the spray operation. The outer wall of the cylinder is provided with a fragrance outlet through which the fragrance liquid is sprayed. However, existing fragrance dispensers have obvious limitations. Their spray direction is often fixed and can only perform a single-point, one-way spray operation. As a result, in actual use, the spray coverage is very limited, making it difficult to meet the requirements for uniform diffusion and wide coverage of the fragrance liquid in different scenarios. For example, in larger spaces such as shopping malls and hotel lobbies, traditional fragrance dispensers can only spray in a fixed direction and position, resulting in low fragrance concentration in areas far from the fragrance outlet, failing to achieve the desired odor improvement effect. Moreover, because the spray direction cannot be adjusted, users cannot flexibly adjust the spray range and direction according to actual needs, which is inconvenient to use and has significant usage limitations. Summary of the Invention

[0003] In view of the shortcomings of the existing technology, the present invention provides a fragrance sprayer to solve the problem that traditional fragrance sprayers can only perform single-point one-way spray operation.

[0004] To achieve the above-mentioned objectives, the present invention provides a fragrance sprayer, comprising a cylinder and a base, wherein the cylinder is provided with a liquid storage tank, a fragrance spray component for connecting to the liquid storage tank to perform a spray operation, and a control module for controlling the opening and closing of the fragrance spray component to suck the liquid in the liquid storage tank, a fragrance outlet is provided on the outer peripheral wall of the cylinder for the fragrance spray component to spray toward the periphery of the cylinder, a first adjustment structure is provided on the base for driving the cylinder to rotate circumferentially so that the spray direction can be circumferentially adjusted, a second adjustment structure is provided between the base and the cylinder for driving the cylinder to move up and down along the height direction of the base so that the spray direction can be height-adjusted, and a third adjustment structure is provided on the cylinder for changing the spray direction along the circumference of the fragrance outlet when the fragrance outlet sprays atomized fragrance liquid.

[0005] The benefits of adopting the above technical solution are: the first adjustment structure in the above technology drives the cylinder to rotate circumferentially, so that the fragrance nozzle can dynamically adjust the spray direction within a range of 360°, solving the problem of spatial coverage blind spots caused by fixed-angle spraying of traditional equipment. In complex scenes such as large shopping malls and office buildings, circumferential adjustment can be used to achieve uniform spraying in the annular area to avoid the phenomenon of local fragrance concentration being too high or too low; at the same time, the second adjustment structure realizes the height adjustment of the cylinder, and can perform precise spraying on air flow layers at different heights. For example, in a hotel lobby, the spray height can be flexibly adjusted according to the height of the crowd (such as standing people and children's activity area) to ensure that the fragrance effectively acts on the target area; and the third adjustment structure changes the spray direction circumferentially of the fragrance nozzle to form fan-shaped, ring-shaped, etc. at the same horizontal height. A variety of spray trajectories, combined with the adjustment functions of the first two, construct a three-dimensional spray coverage system; the liquid storage tank and the fragrance spray component in the above technology are both existing technologies, so their linkage mode and spray mode will not be described in detail. At the same time, the control module is also existing technology, which can use multiple sensors for data collection (temperature sensor, moisture sensor), and the control module performs the first adjustment structure or the second adjustment structure or the third adjustment structure or the two-two linkage or the three-way linkage on and off control according to the collected information. The control module is existing technology and can use intelligent information processing units such as single-chip microcomputers or control chips. Because it is existing technology, its structure and function will not be described in detail.

[0006] The present invention is further provided with: a rotating groove is opened on the end surface of the base, the first adjustment structure includes a turntable rotatably arranged in the rotating groove and a driving motor arranged in the base, the output end of the driving motor is coaxially connected to the bottom wall of the turntable, the cylinder is arranged on the top wall of the turntable, and the driving motor is communicatively connected to the control module.

[0007] The benefits of adopting the above technical solution are: the drive motor in the above technology serves as a power source and is communicated with the control module, which can realize precise angle control of the rotation of the barrel and meet the needs of fine adjustment of the spray direction in different scenarios. For example, in a museum display case, the control module can be set to rotate 5° every 10 minutes, so that the fragrance evenly covers multiple display case areas without affecting the exhibits; and the turntable is arranged in the rotating groove to form a stable rotating support structure, which avoids axial deviation or shaking when the barrel rotates and ensures the stability of the spray direction; the drive motor in the above technology is existing technology, so its structure, size and function will not be described in detail.

[0008] The present invention is further provided with: the second adjustment structure includes two slide rails opened along the height direction of the cylinder, the slide rails are opened in a strip shape and the slide rails are arranged on the top wall of the turntable, the two slide rails are arranged opposite to each other, and the bottom wall of the cylinder is provided with two slide grooves along its height direction, the two slide grooves correspond one-to-one to the two slide rails, and each slide rail is arranged in the corresponding slide groove, the second adjustment structure also includes two groups of climbing components, the two groups of climbing components are arranged one-to-one to the two slide rails, the cylinder corresponding to the two groups of climbing components positions are provided with a drive cavity, the two drive cavities correspond one-to-one to the two slide grooves and are connected, the climbing component includes a climbing gear and a small motor for driving the climbing gear to rotate, the output end of the small motor is coaxially connected with the climbing gear, the climbing gear and the small motor are both arranged in the corresponding drive cavity, and the climbing gear partially passes through the drive cavity to the slide groove, the bottom wall of the slide rail is provided with climbing tooth grooves along the opening direction of the slide rail, the two climbing gears are meshed with the climbing tooth grooves on their respective adjacent slide rails, and the small motor is communicatively connected to the control module.

[0009] The benefits of adopting the above technical solution are: in the above technology, the user sets the target height of the cylinder through the control interface (that is, the height range that the cylinder can climb is preset in the control module), the control module parses the instruction and calculates the required number of lifting steps (based on the slide rail tooth pitch and the motor step angle), the control module sends a drive signal to the small motor, the motor output shaft drives the climbing gear to rotate, the gear engages with the climbing tooth groove on the bottom wall of the slide rail, generating an upward or downward driving force, the slide rail is embedded in the slide groove on the bottom wall of the cylinder, and under the drive of the climbing gear, the cylinder moves linearly along the height direction of the slide rail. During the lifting process of the cylinder, the first adjustment structure can work synchronously or asynchronously (such as lifting and rotating at the same time) to form a compound motion trajectory. After reaching the target height, the third adjustment structure is started to adjust the circumferential spray direction of the fragrance nozzle to achieve precise spraying in three-dimensional space; in the above technology, the up and down reciprocating motion of the cylinder can be achieved by setting the height range and setting the cyclic rotation of the small motor, that is, the forward and reverse rotation of the small motor is set to achieve the up and down reciprocating cyclic lifting and lowering of the cylinder.

[0010] The above technology realizes automatic and precise adjustment of the height of the cylinder through the cooperation of the slide rails, slide grooves and climbing components. First, the two sets of relatively arranged slide rails and slide grooves form a stable guiding structure to prevent the cylinder from tilting or getting stuck when it is lifted or lowered. The climbing gear engages with the climbing tooth grooves on the bottom wall of the slide rails for transmission, so that when the small motor is started, the cylinder can climb along the height direction of the base, thereby realizing the up and down displacement of the cylinder, so that the atomized fragrance liquid sprayed from the fragrance nozzle can be accurately sprayed at air flow layers of different heights; the small and medium motors in the above technology are existing technologies, so their structure and functions will not be described in detail; in the above technology, limit switches can be set at the top and bottom ends of the slide rails. When the cylinder reaches the limit position, the switch is triggered, and the control module sends a stop signal to avoid excessive lifting and lowering. At the same time, the motor encoder feeds back the number of rotations in real time, and the control module synchronously calculates the current height of the cylinder to realize closed-loop control. The technical structure and technical principles are existing technologies and can be added or deleted according to actual needs. Because it is existing technology, its structure and function will not be described in detail.

[0011] The present invention is further provided with: a plurality of movable holes are evenly distributed on the top wall of the slide rail along the direction in which the slide rail is opened, a ball is rolled in each of the movable holes, and the plurality of balls pass through their respective corresponding movable holes and are abutted against the inner wall of the slide groove, and the diameter of the opening of the movable hole is smaller than the diameter of the ball.

[0012] The benefits of adopting the above technical solution are: the ball design on the top wall of the slide rail in the above technology significantly improves the smoothness and reliability of the cylinder lifting and lowering, that is, the ball in the movable hole abuts against the inner wall of the slide groove, converting the traditional sliding friction into rolling friction, thereby reducing the friction coefficient and thus reducing the driving power of the small motor, thereby extending the service life of the motor.

[0013] The present invention further provides that: the slide rail is arranged in a spiral shape, and the two groups of slide rails are combined to be arranged in a cross double helical shape.

[0014] The benefits of adopting the above technical solution are: in the above technology, the slide rail is designed to be spiral, and the two sets of slide rails are in a cross-double helix structure, which gives the cylinder the compound motion ability of circumferential rotation during the lifting process. Traditional linear slide rails can only achieve vertical lifting and lowering, while the spiral slide rail enables the cylinder to rotate synchronously clockwise when rising and counterclockwise when descending, forming a spray trajectory similar to the Archimedean spiral. This motion mode can expand the spray coverage of a single height plane to a three-dimensional spiral coverage, and can achieve 360° annular space without dead angle spraying. The cross-double helix structure ensures that the cylinder is subjected to uniform force when it is lifted and lowered, avoiding the eccentric torque that may be generated by the single helix structure. After mechanical simulation analysis, this structure can reduce the shaking amplitude of the cylinder. In the aromatherapy therapy scene, the spiral spray trajectory, combined with the aerodynamic characteristics of fragrance diffusion, can form a spiral rising fragrance flow field, thereby prolonging the residence time of the fragrance in the space; in the above technology, the slide rail is arranged in a spiral shape and the combination is in a double helix shape, which is beautiful, improves the ornamental value, and makes the cylinder structure compact.

[0015] The present invention further provides that: a limiting groove is circumferentially provided on the inner circumferential wall of the rotating groove, a limiting ring is circumferentially provided on the outer circumferential wall of the turntable for being placed in the limiting groove, a bearing is provided between the limiting groove and the limiting ring, the outer circumferential wall of the outer ring of the bearing is connected to the inner circumferential wall of the limiting groove, and the inner circumferential wall of the inner ring of the bearing is connected to the outer circumferential wall of the limiting ring.

[0016] The benefits of adopting the above technical solution are: in the above technology, the outer ring of the bearing is fixed to the limit groove, and the inner ring is connected to the limit ring, so that the rotation of the turntable in the groove is converted into low-friction rotation of the bearing, the rotational resistance torque is reduced, and the energy consumption of the driving motor is reduced accordingly. The limit ring is embedded in the limit groove to form an axial limit structure, which prevents the turntable from axial movement when rotating at high speed, thereby ensuring the circumferential rotation accuracy of the cylinder.

[0017] The present invention is further provided with: a thread groove is opened in an annular direction on the outer peripheral wall of the cylinder, two relatively arranged limit plates are opened on the turntable along the height direction of the cylinder, the radial cross-section of the limit plate is arc-shaped, and the inner peripheral wall of the limit plate is evenly distributed along the opening direction thereof with a number of limit ridges for cooperating with the thread of the thread groove.

[0018] The benefits of adopting the above technical solution are: in the above technology, a threaded groove and a limiting ridge are set between the cylinder and the turntable to construct a circumferentially rotating limiting guide mechanism, the arc-shaped cross-section of the limiting plate fits with the threaded groove of the cylinder, and the limiting ridge is engaged with the threaded groove, so that when the cylinder rotates up or down, the cylinder is limited from escaping from the base, thereby limiting the cylinder from tilting or overturning. At the same time, the support strength of the cylinder is improved by the setting of the limiting ridge and the limiting plate, that is, part of the force exerted by the weight of the cylinder can act on the limiting plate, thereby preventing the force exerted by the cylinder from being too large, causing the slide rail to be damaged by excessive force.

[0019] The present invention is further provided with: an air cavity is opened circumferentially on the cylinder body, the air cavity is arranged in a ring shape and the axis of the air cavity is arranged coaxially with the fragrance spray port, the third adjustment structure includes a micro air pump arranged in the cylinder body, the air outlet end of the micro air pump is connected to the air cavity, and a plurality of air holes are evenly distributed circumferentially on the inner circumferential wall of the fragrance spray port, and the plurality of air holes are all connected to the air cavity.

[0020] The benefits of adopting the above technical solution are: in the above technology, through the design of the air cavity, micro air pump and air holes, a dynamic adjustment mechanism for the circumferential spray direction of the fragrance nozzle is constructed. The micro air pump delivers compressed air to the air cavity, and the air is ejected through the circumferentially distributed air holes to form an airflow guide field, which pushes the atomized fragrance liquid to diffuse in different circumferential directions. The air cavity and the fragrance nozzle are coaxially arranged to ensure that the airflow acts evenly on the atomized fragrance liquid to form a wide range of angle spray. When local focused spraying is required (such as locating the source of odor), the air holes in a certain direction can be opened separately through the control module to achieve precise directional spraying; the micro air pump in the above technology is existing technology, so its structure and function will not be described in detail.

[0021] The present invention is further provided with: an adjustment groove is annularly opened on the inner circumferential wall of the air cavity, and several of the air holes are connected to the adjustment groove; an isolation ring for closing the several air holes is rotatably set in the adjustment groove; a notch is opened on the isolation ring for any one of the several air holes to be connected to the adjustment groove; the third adjustment structure also includes a micro motor arranged in the cylinder; the output end of the micro motor is coaxially connected to a transmission gear; the outer circumferential wall of the isolation ring is evenly distributed with transmission teeth and grooves; the transmission gear partially penetrates the adjustment groove and is meshed with the transmission teeth and grooves.

[0022] The benefits of adopting the above technical solution are: in the above technology, the selective opening of the air hole is achieved through the isolation ring and the transmission gear, further improving the accuracy of the spray direction control. The gap of the isolation ring only allows a single air hole to be connected to the air cavity. The isolation ring is driven to rotate by a micro motor, and the air holes in different directions can be switched to work in turn, so that in specific scenarios, one-way single-point aerosol spraying can be achieved by driving the rotation of the isolation ring.

[0023] The present invention further provides that: a slot for placing the liquid storage tank in or out of the barrel is provided on the bottom wall or the outer peripheral wall of the barrel, a sealing plate for closing the slot is detachably provided on the slot, and a suction cup is detachably provided on the bottom wall of the base.

[0024] The benefits of adopting the above technical solution are: the above technology improves the usability and installation adaptability of the equipment through the design of slots, sealing plates and suction cups. The slots on the bottom wall or side of the cylinder allow the liquid storage tank to be disassembled, and the sealing plate can be connected by magnetic suction or snap-on connection to ensure sealing while facilitating quick opening and closing; the setting of the suction cup allows the cylinder to be adsorbed on smooth surfaces such as tiles and glass, avoiding displacement of the equipment during adjustment. It is suitable for temporary placement scenarios such as desktops and counters. For scenarios that require fixed installation, the suction cup can be replaced with a bolt mounting base to achieve a variety of installation methods, significantly improving the compatibility of the equipment in different usage scenarios.
