Description

Technical Field

[0001] This utility model relates to the technical field of beverage preparation equipment, specifically a liquid level monitoring device for a tea bar machine. Background Technology

[0002] Tea bar machines are a popular type of home appliance, suitable for businesses, tea rooms, hotels, restaurants, and even private residences. Most tea bar machines use built-in bottled water as their water source, offering advantages over traditional water dispensers such as a more aesthetically pleasing design and smaller overall size. However, a drawback is the difficulty in monitoring the bottled water usage in real time. Often, the bottled water is only replaced when it stops dispensing, which can lead to a less than ideal user experience when entertaining guests.

[0003] An investigation of existing patents and related products revealed that there are relatively few liquid level detection devices installed on tea bar machines, and those that are installed often have unclear display effects, which may result in a poor user experience. Utility Model Content

[0004] The purpose of this invention is to provide a liquid level monitoring device for a tea bar machine, which overcomes the above-mentioned defects in the prior art.

[0005] According to the present invention, a liquid level monitoring device for a tea bar machine includes a control mechanism installed inside the tea bar machine and a monitoring and display mechanism installed on the side panel of the tea bar machine;

[0006] The control mechanism includes a guide rail fixedly installed on the inside of the side panel of the tea bar machine, a slider sliding on the guide rail, a rope fixedly connected to the slider, a fixed pulley seat fixedly installed at the top inside the tea bar machine, the rope passing through the fixed pulley seat and the end fixedly connected to a counterweight ball, and a protective frame fixedly installed on the inside of the side panel of the tea bar machine.

[0007] The monitoring and display mechanism includes a first connecting rod fixed to one side of the slider and a second connecting rod on the other side of the slider. A pressing plate is fixed to the end of the second connecting rod. The first connecting rod passes through a groove in the side panel of the tea bar machine and is fixedly connected to a light-blocking plate. The light-blocking plate is set inside the observation window, which is fixed to the outside of the side panel of the tea bar machine. The top of the observation window is open, and a control module fixed to the side panel of the tea bar machine is fixedly installed at the top of the observation window. Several laser lights are evenly distributed on the control module. Some of the laser lights form the first light source, some of the laser lights form the second light source, and the remaining laser lights form the third light source. A switch plate is fixedly installed on the side panel of the tea bar machine behind the guide rail. A first micro switch, a second micro switch, and a third micro switch are fixedly installed on the switch plate. The first micro switch is used to control the power on and off of the first light source, the second micro switch is used to control the power on and off of the second light source, and the third micro switch is used to control the power on and off of the third light source.

[0008] Ideally, the weight of the counterweight ball should be greater than the tension of the slider on the rope.

[0009] Preferably, the density of the counterweight ball should be less than that of water.

[0010] As a preferred option, the observation window is made of a material that is both impact-resistant and has good light transmission.

[0011] As a preferred option, the light-blocking sheet is made of a material that has good light-blocking performance and is relatively lightweight.

[0012] As a preferred option, light-blocking strips can be installed on both sides of the observation window.

[0013] Preferably, the guide rail is provided with symmetrical mounting brackets on both sides for fixed connection with the side panel of the tea bar machine, and the two mounting brackets are used to fix the guide rail.

[0014] The beneficial effects of this utility model are as follows: This application uses the floating status of a counterweight ball in bottled water as a power source to reflect the liquid level in the tea bar machine in real time. Power is transmitted through a fixed pulley at the top of the tea bar machine. The activation of the first light source, the second light source, and the third light source are controlled according to different bottled water levels. Different colors of light are used to reflect the current liquid level in real time. In addition, a light-blocking plate that rises and falls together is equipped to control the length of the light, making the liquid level feedback more obvious and interesting. Thus, the liquid level detection function of the tea bar machine is well realized, and a good user experience is guaranteed for customers. Attached Figure Description

[0023] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe a liquid level monitoring device for a tea bar machine or several specific implementations of this utility model, and does not strictly limit the scope of protection specifically claimed by this utility model. As used herein, the terms up / down and left / right are not limited to their strict geometric definitions, but rather include tolerances for reasonable and inconsistent machining or human errors. The specific features of this liquid level monitoring device for a tea bar machine are described in detail below:

[0024] Reference Figures 1-7 A liquid level monitoring device for a tea bar machine according to an embodiment of the present utility model includes a control mechanism installed inside the tea bar machine and a monitoring and display mechanism installed on the side panel of the tea bar machine;

[0025] The control mechanism includes a guide rail 11 fixedly installed on the inner side of the side panel of the tea bar machine. A slider 22 is slidably mounted on the guide rail 11. A pressing plate 14 is fixed on one side of the slider 22. A rope 15 is fixedly connected to the slider 22. A fixed pulley seat 16 is fixedly installed at the top inside the tea bar machine. The rope 15 passes through the fixed pulley seat 16 and is fixedly connected to a counterweight ball 17 at its end. The counterweight ball 17 is connected to the slider 22 on the guide rail 11 through the rope 15. The guide rail 11 is fixedly installed on the side panel of the tea bar machine. As the counterweight ball 17 moves, it pulls the rope 15 to drive the slider 22 to move up and down. A protective frame 12 is also fixedly installed on the inner side of the side panel of the tea bar machine. The protective frame 12 is used to protect the control mechanism and has an opening.

[0026] Specifically, when the counterweight ball 17 is placed into the bottled water (a hole needs to be made in the bottled water cap of the tea bar machine to facilitate the placement of the counterweight ball 17), it floats on the bottled water and moves up and down with the height of the bottled water, thereby tightening or releasing part of the rope 15, so that the slider 22 can move up and down.

[0027] The monitoring and display mechanism includes a first connecting rod 21 fixed to one side of the slider 22 and a second connecting rod 23 on the other side of the slider 22. A pressing plate 14 is fixed to the end of the second connecting rod 23. The first connecting rod 21 passes through the groove 20 on the side panel of the tea bar machine and is fixedly connected to the light-blocking plate 25. The light-blocking plate 25 is set inside the observation window 18, which is fixed to the outside of the side panel of the tea bar machine. The top of the observation window 18 is open, and a control module 19 fixed to the side panel of the tea bar machine is fixed at the top of the observation window 18. Several laser lights 26 are evenly distributed on the control module 19. Some of the laser lights 26 form the first light source, some of the laser lights 26 form the second light source, and the remaining laser lights 26 form the second light source. The first, second, and third light sources together form a light source module. A switch plate 24 is fixedly installed on the side panel of the tea bar machine on the rear side of the guide rail 11. A first micro switch 13, a second micro switch 27, and a third micro switch 28 are fixedly installed on the switch plate 24. The switch plate 24, the first micro switch 13, the second micro switch 27, and the third micro switch 28 together form a switch module. The switches on the switch module are used to control the power supply of the light sources in the light source module. The first micro switch 13 is used to control the power supply of the first light source, the second micro switch 27 is used to control the power supply of the second light source, and the third micro switch 28 is used to control the power supply of the third light source.

[0028] Specifically, when there is no bottled water or the bottled water is very little, the straight part of the press plate 14 will press the drive rod of the first micro switch 13, which will power on the first light source corresponding to the first micro switch 13. At this time, each laser lamp 26 in the first light source will emit a kind of diffused light, which is convenient for the user to observe through the observation window 18. In addition, the light blocking plate 25 will block the light of each laser lamp 26 in the first light source, thereby controlling the length of the light. Similarly, when there is a lot of bottled water, the press plate 14 will press the third micro switch 28, thereby controlling the third light source to be powered on, and the corresponding light length is the longest. When the bottled water is of average quality, the press plate 14 will press the second micro switch 27, thereby controlling the second light source to be powered on. The first light source, the second light source, and the third light source can use red, yellow, and green colors respectively to achieve different warning effects.

[0029] Beneficially, the weight of the counterweight ball 17 is greater than the tension of the slider 22 on the rope 15.

[0030] Beneficially, the density of the counterweight ball 17 is less than that of water, allowing the counterweight ball 17 to float on the water surface in real time.

[0031] Beneficially, the observation window 18 is made of a material that is impact-resistant and has good light transmission; acrylic sheet, PC sheet, or other similar materials could be considered.

[0032] Beneficially, the light-blocking sheet 25 should be made of a material that has good light-blocking performance and is relatively lightweight; PVC or PMMA resin could be considered.

[0033] Beneficially, light-blocking strips can be installed on both sides of the observation window 18 to prevent light from spreading to both sides and enhance the visual effect.

[0034] Beneficially, the guide rail 11 is provided with symmetrical mounting seats 10 on both sides, which are fixedly connected to the side panel of the tea bar machine. The two mounting seats 10 are used to fix the guide rail 11.

[0035] Beneficially, the third light source can use a softer color to represent sufficient water, the second light source can use a brighter color to represent that a lot of water has been used, and the third light source can use an extremely bright color to represent that there is basically no water or that no bottled water has been used. Common colors are green, yellow, and red.

[0036] Those skilled in the art will appreciate that various modifications to the above embodiments can be made without departing from the overall spirit and concept of this utility model. All such modifications fall within the protection scope of this utility model. The protection scheme of this utility model is defined by the appended claims.
