Description

Technical Field

[0001] The utility model relates to the technical field of maternal and infant products, in particular to a maternal and infant device capable of detecting water flow rate. Background Art

[0002] The structure of traditional milk mixers is mostly to place a kettle on the base, and the user sets the required heating temperature to directly heat the cold water in the kettle; after heating, lift the kettle and pour the hot water into the bottle to brew milk powder, etc. On this basis, in order to improve the convenience of water use for users, corresponding electric water pumping mechanisms and water outlets are set on the base. By pressing the corresponding control switch, the electric water pumping mechanism pumps the water in the kettle to the water outlet, making it more convenient to collect water for use.

[0003] When preparing milk, water of a corresponding volume is usually used according to the growth stage of the baby, such as 150 ml. Therefore, milk preparing devices capable of quantitative water discharge are constantly being developed. For example, the Chinese utility model "constant temperature milk preparing device with quantitative water discharge function" with announcement number CN219629394U proposes a control method of quantitative water discharge by timing control of water discharge through a timing module, but the quantitative water discharge is relatively fixed. If the water discharge volume needs to be adjusted, the adjustment process is relatively complicated.

[0004] Another example is the Chinese utility model "Instant Hot Milk Mixer" with announcement number CN218338217U, which uses a water flow meter to detect water flow, combined with corresponding valve control, to achieve arbitrary quantitative control. Although its quantitative control accuracy is good, the water flow meter currently used in this type of milk mixer on the market needs to be installed in the water pipe to detect the water flow. On the one hand, it is difficult to install, and on the other hand, it is easy to reduce the cleanliness of the pipe during disassembly, assembly and maintenance, which is not conducive to ensuring the safety of infant water, and needs to be improved.

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] See also Figure 1-3 A maternal and infant device capable of detecting water flow rate comprises a water-boiling base 1, a kettle 2 and a connecting component 3, wherein the connecting component 3 is used to connect the kettle 2 with a conducting pipe 9 after the kettle 2 is placed at a corresponding position on the water-boiling base 1. A water pump 4, a controller 5, an ultrasonic flowmeter 6 and a water outlet 7 are arranged on the water-boiling base 1, the water outlet of the water pump 4 is connected with the water outlet 7 through a water outlet pipe 8, and the water inlet of the water pump 4 is connected with a conducting pipe.

[0024] The ultrasonic flow meter 6 includes a transmitter 601 installed on the outside of the water outlet pipe 8 and a receiver 602 installed on the outside of the water outlet pipe 8 and cooperating with the transmitter. The ultrasonic flow meter 6 also includes a signal processing unit electrically connected to the controller 5, the signal receiving end of the signal processing unit is electrically connected to the signal end of the receiver 602, the signal receiving end of the signal processing unit obtains the electrical signal converted by the receiver 602 after receiving the ultrasonic signal, and the signal end of the signal processing unit is electrically connected to the signal end of the controller 5.

[0025] The improvement is that the transducer designated as the transmitter 601 transmits an acoustic pulse to the fluid in the outlet pipe 8, and the transducer designated as the receiver 602 receives the acoustic pulse outside the outlet pipe 8, and then the flow rate and cumulative volume of water are obtained according to the time taken for the acoustic pulse to propagate from the transmitter 601 to the receiver 602, that is, the time difference method, and the size information of the outlet pipe 8 are integrated. After the improvement, the ultrasonic flow meter 6 is used for detection, so that the controller 5 can obtain the corresponding water output information, and then make, for example, quantitative water output control; and the ultrasonic flow meter 6 is installed in a non-invasive manner, which is more conducive to maintenance, and effectively ensures the cleanliness of the water in the pipeline after maintenance.

[0026] In this embodiment, the water outlet pipe 8 includes a first connecting section 801 connected to the water pump 4, a second connecting section 802 connected to the water outlet 7, and a measuring section 803 connecting the first connecting section 801 and the second connecting section 802, and the transmitter 601 and the receiver 602 are installed on the measuring section 803.

[0027] Furthermore, an electrically controlled conduction valve 10 for opening / closing the second communication section 802 is provided on the second communication section 802, and a control end of the electrically controlled conduction valve 10 is electrically connected to the controller 5. The electrically controlled conduction valve 10 is preferably a solenoid valve.

[0028] In some embodiments, the quantitative water output can be controlled by controlling the corresponding water pump 4 to stop working, or controlling the corresponding solenoid valve to close the water passage when the accumulated volume reaches a preset amount.

[0029] In this embodiment, the measuring section 803 of the water outlet pipe is a straight pipe section, which is more conducive to improving the accuracy of ultrasonic detection.

[0030] Preferably, the measuring section 803 of the water outlet pipe is vertically arranged, and is configured so that when the water pump 4 is pumping water, the water passes through the measuring section 803 from bottom to top in the measuring section 803 .

[0031] like Figure 2 As shown, the measuring section 803 is formed with a high communication port 8031 ​​and a low communication port 8032.

[0032] When the water pump works to pump water out of the water outlet 7, the water flows from the water outlet of the water pump 4 through the first connecting section 801, and then flows upward from the low-level connecting port 8032 of the measuring section 803 to the high-level connecting port 8031 ​​of the measuring section 803, and finally reaches the water outlet 7 through the second connecting section 802.

[0033] Under the action of gravity, when the water passes through the measuring section 803, the water flow cross-sectional area of ​​the water is the same as or nearly the same as the water flow cross-sectional area of ​​the pipe section, which is more conducive to improving the accuracy of water flow detection.

The transmitter 601 and the receiver 602 are respectively mounted on the first mounting seat 603 and the second mounting seat 604 and correspond to the water outlet pipe 8.

[0035] Preferably, the first mounting seat 603 and the second mounting seat 604 are clamps detachably connected to the water outlet pipe 8. The pipe straightener 605 includes a connecting straight rod to form a straightening and holding mechanism for the water outlet pipe 8.
