Description

Technical Field

[0001] The present application relates to the field of household appliances, and in particular to a tea bar machine. Background Art

[0002] At present, most tea bar machines on the market have the following two sterilization methods: the first is to pump the water in the bucket into the water tank and sterilize it inside the water tank. This method requires water to pass through multiple pipes, which greatly increases the risk of water contamination. In addition, the sterilization lamp is located above the water tank. As the water level decreases, the light is farther away from the water source, which further reduces the sterilization effect. The second is to use a flow-through sterilization device. When the user uses it, the water flows through the flow sterilization device for sterilization. The sterilization effect of this method is greatly affected by the water flow rate, and the sterilization effect is unstable.

[0003] The above two sterilization methods cannot inhibit the growth of bacteria from the source. Moreover, after the tea bar machine has been used for a long time, the water storage and pumping pipes will be contaminated by bacteria, causing the user to be directly contaminated when changing the water next time. Utility Model Content

[0004] In order to solve the above problems, the present application proposes a tea bar machine, comprising: a back panel and a cabinet, wherein the cabinet is provided with a water storage container and a push plate for placing the water container, and wherein the water storage container is provided with a water pump and a sterilization component arranged on the water pump, wherein the water storage container is provided with a water pump and the water pump extends to the bottom of the water storage container, and a power supply device is provided outside the water storage container, and the power supply device supplies power to the sterilization component by electromagnetic induction.

[0005] In one example, the sterilization component is fixed to the bottom of the water pump, and the power supply device includes a power supply coil arranged at the bottom of the push plate, and the power supply coil is wirelessly connected to a receiving coil arranged on the sterilization component.

[0006] In one example, the sterilization assembly includes a water flow piece, a sterilization device and a countersunk head. A limiting rib is provided on the inner side of the countersunk head. The limiting rib cooperates with the water flow piece to install and fix the sterilization device between the water flow piece and the countersunk head.

[0007] In one example, a sealing ring is further provided between the countersunk head and the water flow piece, and the sealing ring is sleeved on the water flow piece and embedded in the countersunk head to achieve sealing.

[0008] In one example, at least one germicidal lamp is provided on the sterilization device, and the germicidal lamp is arranged toward the water outlet of the water storage container, and the shell of the countersunk head is a transparent structure.

[0009] In one example, the sterilization component can be movably mounted on the outer wall of the water pump, a cylindrical push plate wall is arranged above the push plate, and the power supply device includes a power supply coil wound on the push plate wall, and the power supply coil is wirelessly connected to a receiving coil arranged on the sterilization component.

[0010] In one example, the sterilization component includes a suspension component and a sterilization device, wherein the sterilization device is installed in the suspension component, and a sealed cabin for storing gas is provided below the sterilization device, and the sealed cabin is in contact with water in a water storage container.

[0011] In one example, the cylindrical push plate wall is integrally formed with the push plate, and the power supply coil extends from the cylindrical push plate wall to the bottom of the push plate.

[0012] In one example, a water level detection device is further provided in the water storage container, and the water level detection device and the sterilization component are both electrically connected to a control module, and the control module controls the sterilization frequency of the sterilization component based on a water level signal of the water level detection device.

[0013] In one example, the power supply device includes an oscillator connected to the power supply coil, the oscillator is used to convert direct current into alternating current, and the sterilization device includes a rectifier circuit and a step-down circuit connected to the receiving coil, the rectifier circuit is used to convert alternating current into direct current.

[0014] The method proposed in this application can bring the following beneficial effects:

[0015] 1. The sterilization component is set inside the water storage container based on wireless charging technology, and it can be powered directly without being connected by a power cord or battery, solving the problem of being unable to directly power the underwater sterilization component, eliminating the power supply line and water-electricity isolation structure used to achieve electrical connection in the prior art, simplifying the structural design of the sterilization component 4, and saving the cost of the whole machine. It solves the problem that the user cannot quickly use up the drinking water in the bucket during the tea bar machine process, and it is easy to cause bacteria to grow if it is left for a long time.

[0016] 2. The sterilization device is set at the bottom of the water pipe through the countersunk head and the water-passing piece. No matter how low the water level is, the stability of the sterilization effect can be guaranteed.

DETAILED DESCRIPTION

[0030] In order to make the purpose, technical solution and advantages of the present application clearer, the technical solution of the present application will be clearly and completely described below in combination with the specific embodiments of the present application and the corresponding drawings. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present application.

[0031] The technical solutions provided by various embodiments of the present application are described in detail below in conjunction with the accompanying drawings.

[0032] like Figure 1 As shown, an embodiment of the present application provides a tea bar machine, including a back panel and a cabinet, wherein a water storage container 1 and a push plate 2 for placing the water container are provided in the cabinet, a water pumping pipe 3 and a sterilization component 4 arranged on the water pumping pipe 3 are provided in the water storage container 1, and the water pumping pipe 3 extends to the bottom of the water storage container 1, and a power supply device is provided outside the water storage container 1, and the power supply device supplies power to the sterilization component 4 by electromagnetic induction.

[0033] In the above, the water storage container 1 of the tea bar machine is of bottom water inlet type, and water is pumped out of the water storage container 1 through the pumping pipe 3. The pumping pipe 3 is located in the center of the water storage container 1 and extends downward to the bottom of the water storage container 1. In a specific implementation of this embodiment, the pumping pipe 3 is in contact with the inner surface of the bottom wall of the water storage container 1 to ensure that all the water in the water storage container 1 can be pumped out by the pumping pipe 3, thereby avoiding the situation where residual water in the water storage container 1 is not used. At the same time, the wireless power supply device with a channel arranged outside the water storage container 1 supplies power to the sterilization component 4, eliminating the power supply line and the water-electricity isolation structure used to achieve electrical connection in the prior art, simplifying the structural design of the sterilization component 4 and saving the cost of the whole machine.

[0034] In one embodiment, Figure 2As shown, the sterilization component 4 is fixed to the bottom of the water pumping pipe 3, and the power supply device includes a power supply coil 503 arranged at the bottom of the push plate 2, and the power supply coil 503 is wirelessly connected to the receiving coil 504 arranged on the sterilization component 4. A universal wheel is arranged at the bottom of the push plate 2, and the user only needs to place the bucket on the push plate 2 and push it into the tea bar machine when using it. Since the water pumping pipe is located at the center of the water storage container 1 and the bottom is in contact with the bottom wall of the water storage container 1, the sterilization component arranged at the bottom of the water pumping pipe 3 is located at the center of the bottom of the water storage container 1, which improves the speed of electromagnetic induction power supply. At the same time, by fixing the sterilization component 4 to the bottom of the water pumping pipe 3, it can prevent the sterilization component 4 from moving with the water flow in the water storage container 1, and ensure the stability of electromagnetic induction power supply. When the power supply coil 503 is arranged in the bottom of the push plate 2, the junction between the bottom of the push plate 2 and the power supply coil 503 is concave, so that the power supply coil 503 is embedded in the bottom of the push plate 2. At the same time, the bottom of the push plate 2 should also be provided with a groove for fixing and embedding the power supply line connected to the power supply coil 503. Embedding the power supply line at the bottom of the push plate 2 can make the overall structure of the tea bar machine more concise and beautiful.

[0035] Unlike the prior art in which the sterilization component 4 is arranged at the top of the water storage container 1, the sterilization component 4 is arranged at the bottom of the water storage container 1. In the process of the water storage container 1 changing from full to empty, its sterilization function can continue to work, and the sterilization effect will not gradually decrease as the liquid level decreases. The push plate 2 provided with a power supply device can not only supply power to the sterilization component 4 at a close distance, but also be used to place and move the water storage container 1. By providing a universal wheel at the bottom of the push plate 2, when there is a large amount of water in the water storage container, the water storage container can be moved by the push plate 2, which can save the user's physical strength.

[0036] In one embodiment, Figure 3 and Figure 4 As shown, the sterilization component 4 includes a water-passing part 401, a sterilization device 402 and a countersunk head 403. A limiting rib is provided inside the countersunk head 403. The limiting rib cooperates with the water-passing part 401, so that the sterilization device 402 can be installed and fixed between the water-passing part 401 and the countersunk head 403. By providing the countersunk head 403 in the sterilization component 4, weight can be provided to the sterilization component 4, so that the sterilization component 4 can be fixed underwater, reducing the effect of buoyancy on the sterilization component 4, and preventing the sterilization component 4 from floating up. At the same time, the limiting rib provided inside the countersunk head 403 fixes the sterilization device 402 between the water-passing part 401 and the countersunk head 403, so as to prevent the sterilization device 402 from moving. At the same time, the water-passing part 401 is provided at the bottom of the water pumping pipe 3. When the user takes water, the water flows from the hollow part of the water-passing part 401 to the water pumping pipe 3, and then flows out of the water storage container 1. The water passing member 401 can cooperate with the water pumping pipe 3 to achieve contact with the inner surface of the bottom wall of the water storage container 1 to avoid water residue.

[0037] In one embodiment, a sealing ring 404 is further provided between the countersunk head 403 and the water flow member 401, and the sealing ring 404 is sleeved on the water flow member 401 and embedded in the countersunk head 403 to achieve sealing. The gap between the countersunk head 403 and the water flow member 401 can be sealed by a sealant, thereby preventing the sterilization device 402 from being ineffective due to water immersion. By providing the sealing ring 404, the connection between the countersunk head 403 and the water flow member 401 can be stabilized, and liquid can be prevented from entering the sterilization component 4.

[0038] In one embodiment, at least one germicidal lamp is provided on the sterilization device 402. The germicidal lamp here is generally an ultraviolet germicidal lamp. The germicidal lamp is arranged toward the water outlet of the water storage container 1, and the shell of the countersunk head 403 is a transparent structure, so that the ultraviolet light emitted by the germicidal lamp can pass through the countersunk head 403 to sterilize the water inside the water storage container 1. When multiple germicidal lamps are provided in the sterilization device 402, the germicidal lamps can be distributed in a matrix or in a circular ring with the water pump 3 as the center. When multiple germicidal lamps are provided, the direction of the germicidal lamps should be corrected, and each germicidal lamp should maintain an angle with the vertical direction of the water pump 3 so that the light emitted by the germicidal lamp can cover more area. The size of the angle is specifically determined by the number of germicidal lamps.

[0039] In one embodiment, in addition to setting the sterilization component 4 at the bottom of the water pumping pipe 3 and continuously sterilizing the water storage container 1, the sterilization component 4 can also be movably sleeved on the outer wall of the water pumping pipe 3 so that the sterilization component 4 can move along the water pumping pipe 3. When the sterilization component 4 is sleeved on the outer wall of the water pumping pipe 3, since the sterilization component 4 may be far away from the bottom of the water storage container 1, the power supply coil 503 at the bottom of the push plate 2 is far away from the receiving coil 504 in the sterilization component 4, resulting in a poor power supply effect. Therefore, the position of the power supply coil 503 can be changed, and a cylindrical push plate 2 wall is further provided above the push plate 2. The power supply device also includes a power supply coil 503 wound on the push plate 2 wall, and the power supply coil 503 is wirelessly connected to the receiving coil 504 provided on the sterilization component 4. In other words, the power supply coil 503 can also be wound around the cylindrical push plate 2 wall. This winding method of the power supply coil 503 only requires the receiving coil 504 to be inductively sensed and powered by the power supply coil 503 inside. At this time, no matter where the sterilization component 4 is sleeved on the outer wall of the water pumping pipe 3, it can be powered by the power supply coil 503 arranged in the wall of the push plate 2. When the sterilization component 4 is sleeved on the outer wall of the water pumping pipe 3, in order to make the sterilization component 4 suspended on the liquid surface in the water storage container 1, the sterilization component 4 is provided with a suspension part and a sterilization device 402, wherein the sterilization device 402 is installed in the suspension part, and a sealed cabin for storing gas is arranged below the sterilization device 402, and the sealed cabin keeps in contact with the water in the water storage container 1, so that the sterilization device 402 in the sterilization component 4 can float with the change of the liquid level.

[0040] At this time, in order to prevent the sterilization device 402 from becoming ineffective when it encounters water, a transparent protective shell can be provided outside the sterilization device 402 to prevent the sterilization device 402 from coming into contact with water. At the same time, the sterilization lamp provided in the sterilization device 402 should be oriented toward the bottom of the water storage container 1, so that the sterilization lamp can sterilize the liquid in the water storage container 1. By providing a transparent protective shell, the sterilization device 402 is protected from being immersed in water while the propagation of the ultraviolet light irradiated by the sterilization lamp is not hindered.

[0041] In one embodiment, the cylindrical push plate 2 wall is integrally formed with the push plate 2, and the power supply coil 503 extends from the cylindrical push plate 2 wall to the bottom of the push plate 2. Since the cylindrical push plate wall is integrally formed with the push plate 2, the fixing effect of the cylindrical push plate wall when placing the water storage container can be ensured. At this time, the power supply coil 503 can extend from the cylindrical push plate wall to the bottom of the push plate 2, so that when the sterilization component is close to the bottom of the water storage container, power can be supplied simultaneously through the power supply coil 503 at the bottom of the push plate 2 and the power supply coil 503 wound in the push plate wall, thereby increasing the power supply efficiency.

[0042] In one embodiment, for a tea bar machine that is fixed and has been turned on for a long time, there may be an unexpected power outage. In this case, an electric energy storage device connected to the sterilization device 402 may be provided in the sterilization component, and when the sterilization component 4 is powered by the power supply coil 503, the excess power may be stored in the electric energy storage device. When the tea bar machine is accidentally powered off, the electric energy storage device may be used to power the sterilization component 4 for a short period of time to prevent the sterilization component 4 from being unable to disinfect the water in the water storage container 1 after an unexpected power outage.

[0043] In one embodiment, a water level detection device is also provided in the water storage container 1, and the water level detection device and the sterilization component 4 are both electrically connected to the control module 501. The control module 501 can control the sterilization frequency of the sterilization component 4 and the operating power of the sterilization device 402 based on the water level signal of the water level detection device, thereby saving power and reducing the life loss of components. The control module 501 can also provide real-time feedback of the liquid level height to the user, reminding the user to change the water in time.

[0044] Specifically, the water level detection device can be an infrared emitting device and an infrared receiving device, wherein the infrared generating device can be arranged on a suspended part, and the infrared receiving device can be arranged at a fixed position, such as the bottom of the water storage container 1, or the bottom of the water storage container 1. Alternatively, the infrared generating device is arranged at a fixed position, and the infrared receiving device is arranged on a suspended part, which is not limited here. In addition, the water level detection device can also detect the water level through a capacitor, or an additional float is arranged in the water storage container 1 for water level detection. Here, the implementation method of the water level detection device is not limited.

[0045] In one embodiment, the control module 501 of the tea bar machine can also control the start and stop or the operating power of the sterilization component 4 within a preset time based on a preset control instruction. For example, when the user sets in advance to reduce the brightness of the germicidal lamp within a certain time period, when entering the time period, the control module 501 reduces the operating power of the sterilization device 402 to reduce the brightness of the germicidal lamp.

[0046] In one embodiment, the power supply device includes an oscillator 502 connected to the power supply coil 503, and the oscillator 502 is used to convert direct current into alternating current. The sterilization device 402 includes a rectifier circuit 505 and a step-down circuit 506 connected to the receiving coil 504, and the rectifier circuit 505 is used to convert alternating current into direct current.

[0047] The various embodiments in the present application are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0048] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
