DETAILED DESCRIPTION

[0027] The present application will be further described in detail below in conjunction with the accompanying drawings and through examples, the following examples are an explanation of the present application and the present application is not limited to the following examples.

[0028] Example 1:

[0029] Reference Figures 1-5The elevator car of the embodiment comprises a car body 101, a fragrance storage part 102, a fragrance 117 output channel and a discharge channel 103, the fragrance storage part 102 comprises a plurality of storage compartments, a first channel 104 is arranged above the storage compartments, the fragrance 117 output channel comprises a ventilation pipeline 105 and an output pipeline 106, the ventilation pipeline 105 is communicated with the output pipeline 106, the ventilation pipeline 105 is arranged outside the box, the output pipeline 106 is arranged inside the car, the storage compartments are provided with fragrance outlet ports 107, the fragrance outlet ports 107 are communicated with the ventilation pipeline 105, the fragrance storage parts and the ventilation pipelines 105 are symmetrically arranged at the top and the bottom of the car body 101, the openings of the ventilation pipelines 105 and the first channels 104 are arranged at the top or the bottom of the car, the discharge channels 103 are arranged at both sides of the car body 101, and the two ends are arranged at the top and the bottom of the car, the discharge channels 103 are communicated with the top and the bottom inclined angle parts of the car through flow guide pipelines 108, the first channels 104 of the plurality of storage compartments are provided with first valve bodies 109, and the first valve bodies 109 are connected with a controller.

[0030] The elevator car is suitable for high-rise or super high buildings according to commercial planning, and can change the gas atmosphere in the car according to the purpose of the passenger, for example, a food floor: the elevator can use food flavoring gas such as coffee, toast and chocolate to simulate the atmosphere before and after meals, and increase the comfort of the whole elevator; an entertainment floor: the elevator can use fresh strawberry, mint, lemon and other fruit flavoring gas to create a relaxed and pleasant atmosphere; the elevator can also use plant fragrances such as bamboo and green leaves commonly used in leisure clubs to bring natural and fresh feeling to users; a business office floor: the elevator can use more stable and elegant fragrances such as osmanthus, clove and tea to create an elegant and comfortable business atmosphere; the elevator can also use lemon, mint and other fresh flavors to relieve office stress; a residential floor: the elevator can use holiday fragrances supplied by IKEA: such as the smell of Christmas tree, the smell of pumpkin for Halloween, and the smell of flowers in spring, to create a romantic, solemn or passionate atmosphere, and make the residents feel comfortable.

[0031] The method for controlling the fragrance in the car according to the present application is as follows: storing various solid volatile fragrances 117 in the storage compartments; when the elevator is going up, if the target floor is the food floor, the first valve body 109 of the storage compartment corresponding to the fragrance 117 on the top of the car is opened, the elevator airflow enters the first channel 104 and the ventilation pipeline 105 from top to bottom, and thus the fragrance gas in the storage compartment with the opened first valve body 109 is introduced into the output pipeline 106 along the airflow, at this time, the airflow from top to bottom is guided out along the output pipeline 106, and due to the Venturi effect, the gas in the car is guided out to the outside along the airflow pipeline 108 in real time, so that the stagnant gas in the car is discharged, and the corresponding first valve body 109 on the food floor in the corresponding section is always opened, so that the car can effectively maintain the corresponding gas, when entering the leisure and entertainment floor for example, the first valve body 109 maintaining the smell of the food floor is closed, and the first valve body 109 maintaining the gas of the leisure and entertainment floor is opened, so that the gas generated in the food floor in the previous stage is guided out and then introduced into the corresponding gas in the leisure and entertainment floor. Therefore, the present method can not only ensure that the fragrance gas matching the floor area is supplied according to the area division of the floor, create a good gas atmosphere, and bring a comfortable experience to the passengers, but also can quickly update the gas after the elevator changes the floor area, further ensure a good experience, and when the elevator is going down, only the first valve body 109 on the top needs to be closed and the corresponding first valve body 109 on the bottom needs to be opened. The present application does not need additional exhaust and air guiding facilities, but uses the airflow power of the elevator going up and down to guide the fragrance gas and discharge the stagnant gas, which can effectively ensure that the elevator has a good gas environment in real time, and at the same time, due to the guiding of the up and down airflows, the gas resistance of the elevator operation is reduced to a certain extent, the efficiency of the elevator operation is increased, and the energy consumption is reduced to a certain extent. Since the present method directly uses the internal gas exchange of the elevator, the elevator shaft needs to be provided with gas discharge and purification facilities to ensure the air quality in the elevator shaft.

[0032] In the present embodiment, the first valve body 109 includes a housing 111, the housing 111 is provided with a through hole for connecting the first channel 104, the housing 111 is provided with a valve cover 112, the valve cover 112 is hingedly arranged on the side of the through hole, the two sides of the valve cover 112 are in contact with the wall surface of the housing 111, the valve cover 112 is drivingly connected with a motor 113, and the motor 113 is connected with a controller.

[0033] Based on the different passenger groups and the changes of passenger feedback to the gas, the atmosphere gas needs to be optimized and updated, so various types of fragrances 117 can be used to match the appropriate ratio to create a multi-dimensional fragrance atmosphere, so various types of fragrances 117 need to be set in the storage compartment and need to be matched appropriately. Therefore, by using the structure, on the one hand, the first channel 104 can be closed to prevent the fragrances 117 in the storage compartment from being quickly discharged (to completely prevent it from being discharged, a second valve body, i.e. a conventional electrically controlled butterfly valve, can be provided at the fragrance outlet port 107), on the other hand, since the size of the through hole of the first channel 104 is fixed, the ventilation volume can be changed by rotating the valve cover 112. The larger the ventilation volume is, the greater the airflow velocity of the storage compartment will be, thereby changing the discharge amount of the fragrances 117 per unit time, so that various fragrances 117 can be matched according to the appropriate ratio to form an appropriate fragrance gas atmosphere. Preferably, the fragrances 117 are solid volatile fragrances 117.

[0034] The output channel and the discharge channel 103 are both provided with V-shaped grooves 114, and the V-shaped groove 114 of the discharge channel 103 is larger than that of the output channel, so that the ventilation volume of the output channel is larger, making the negative pressure effect better and the internal air of the car better and timely discharged.

[0035] In the embodiment, the output duct 106 is arranged longitudinally with the side wall of the car, the air outlet plate 115 of the output duct 106 is provided with double-layer plate, and a plurality of air outlet micro-holes 116 are arranged on the double-layer plate. The air outlet micro-holes 116 of the double-layer plate are arranged in a staggered manner, which helps to reduce airflow noise and facilitates uniform introduction of side gas, thereby facilitating uniform diffusion in the car to form a good gas effect.

[0036] Embodiment 2:

[0037] In order to adapt to the mixing ratio adjustment of different fragrances, a new fragrance storage part structure is provided in this embodiment, wherein the first valve body comprises a first frame 201, the first frame 201 is connected with the second frame 202 of the direction storage part through a bolt structure, the first frame 201 and the second frame 202 are provided with a ventilation hole 203, the first frame 201 is provided with an air inlet adjusting module, the air inlet adjusting module comprises a moving cover 204, an adjusting plate 205, a lead screw motor 206 and a fixed block 207, the adjusting plate 205 is rotationally arranged on the side plate 208 of the moving cover 204, the side plate 208 is provided with an arc-shaped groove 209 matched with the rotation of the adjusting plate 205, the moving cover 204 is slidingly arranged on one side of the ventilation hole 203, the lead screw motor 206 is slidingly arranged on the sliding groove 210 at the bottom of the moving cover 204 and is threadedly matched with the fixed block 207 of the bottom plate of the first frame 201, the bottom of the adjusting plate 205 is provided with a connecting inclined block 211, the connecting inclined block is provided with an inclined groove 212, the inclined groove 212 is matched with a roller set 213, the roller set 213 is connected with the shell of the lead screw motor 206 through a connecting rod 214, the first frame 201 is provided with a pre-tightening block 215, the pre-tightening block 215 is slidingly arranged in the mounting groove of the first frame 201 through a spring, the two sides of the pre-tightening block 215 are provided with an inclined angle or an arc-shaped angle, the pre-tightening block 215 is in contact with the side plate 208 in the initial state, one side of the first frame 201 is provided with a U-shaped plate 216, both ends of the U-shaped plate 216 are slidingly arranged in the insertion groove of the side of the first frame 201, the U-shaped plate 216 is connected and fixed with the side plate 208, and the U-shaped plate 216 slides on the extended bottom plate of the first frame 201.

[0038] In the embodiment, based on the above structure, in the first adjusting working position: the lead screw motor 206 is in action, and since the lead screw motor 206 is slidably arranged on the sliding groove 210, it moves along the sliding groove 210, and the roller set 213 moves in the inclined groove 212, thereby pushing the adjusting plate 205 to rotate around the hinge point. This working position can change the air inlet amount, thereby changing the amount of discharged fragrance gas per unit time. Due to the effect of the pre-tightening block 215, the moving cover 204 cannot be moved, and in this stage, the size of the air inlet is not changed. In the second adjusting working position, since the adjusting plate 205 is rotated to the limit position, the lead screw motor 206 continues to move, thereby breaking the pre-tightening force of the pre-tightening block 215, and driving the moving cover 204 to move to the front side. At this time, the air inlet gradually decreases, thereby driving the moving cover 204 to move to the other side, synchronously driving the U-shaped plate 216 to reduce the area of the air inlet. Under the action of the U-shaped plate 216, the relative air inlet amount basically remains unchanged, thereby helping to improve the air flow rate per unit, and further improving the amount of fragrance gas. Through the above two ways, the adjustment of the amount of fragrance gas can be effectively ensured, and in the process of combining and mixing gas by combining a plurality of fragrance storage parts, good adjusting effect is obtained, and personnel in the field can match the appropriate working position according to the demand in the process of mixing fragrance gas. In the embodiment, since the working state of the first adjusting valve is complex, in actual operation, in order to quickly enter the next adjusting state, in the case that the corresponding fragrance storage part needs to be immediately closed, the second valve body (butterfly valve) can be immediately closed, and the first valve body is used to close the air inlet.

[0039] In the embodiment, the inner side of the adjusting plate 205 is provided with a rubber strip 207, so that when the moving cover 204 moves to the position of closing the air inlet, the rubber strip 207 contacts and seals the inner side of the air inlet, so that after the moving cover 204 moves to the limit position, the rubber strip 207 contacts the front side of the air inlet, thereby ensuring the relative sealing of the air inlet.

[0040] In the embodiment, in order to further improve the emission diversity of the fragrance, the storage compartment comprises a box body 218, a plurality of unit cells 219 for storing the fragrance are arranged in the box body 218, an air inlet groove 220 is arranged on the rear side of the box body 218, an air outlet 221 is arranged at the front end of the unit cell 219, a plurality of air inlet openings 222 are arranged at the rear end of the unit cell 219 and are in communication with the air inlet groove 220, the air inlet opening 222 is matched with an adjusting belt mechanism, the adjusting belt mechanism comprises a sliding rod 223, a traction line 224, a winding device 225 and a belt 226, one end of the traction line 224 is slidingly connected, both ends of the belt 226 are fixedly connected with the traction line 224 on both sides, the other end of the traction line 224 is connected with the winding device 225, the winding device 225 is provided with a spiral spring for winding the traction line 224, the belt 226 is arranged on the outer side wall surface of the air inlet opening 222, the adjusting belt mechanism is provided with a plurality of wheel groups matched with the sliding direction of the traction line 224 and the belt 226. The sliding rod 223 is slidingly arranged on the bottom plate of the first frame 201, and the sliding rod 223 is rotationally connected with the screw rod of the lead screw motor 206. Therefore, in the embodiment, during the above adjustment process, the screw rod of the lead screw motor 206 drives the sliding rod 223 to slide to the front side, then gradually drives the belt 226 to disengage from the air inlet opening 222, then during the air inlet process, the air enters from the air inlet opening 222 and exits from the air outlet 221, further improving the carried-out fragrance gas, and as gradually moving forward, the air inlet opening is gradually opened, gradually improving the carried-out fragrance gas, after returning to the rear position, the winding device 225 is provided with a spiral spring, which resets the traction line 224, so that the belt 226 is reattached to the air inlet opening 222. In the embodiment, the air outlet 221 is provided with an elastic diaphragm 227 on the upper side, the box body 218 is provided with a placement platform 228 for placing solid fragrance, and the rear side of the platform is provided with a wind collecting groove 229.
