Description

Technical Field

[0001] This utility model belongs to the field of cleaning appliances, and in particular relates to a vacuum cleaner that avoids high-temperature operation of the motor. Background Technology

[0002] A vacuum cleaner is a cleaning tool, which can be categorized by structure into upright, canister, and portable types. Vacuum cleaners are equipped with a brush head for sucking up dust and debris. The vacuum cleaner brush head is a shell structure with a suction port, containing a motor and blades. During vacuuming, the motor drives the blades to rotate at high speed, creating negative air pressure inside the shell to suck up dust and debris. Existing vacuum cleaner brush heads have a suction port at the bottom. When the brush head picks up fabric, the fabric can easily clog the suction port. When the suction port is clogged, air cannot enter the vacuum cleaner, and the motor cannot dissipate heat in time, leading to overheating and potential damage to the machine. Utility Model Content

[0010] As a further description of the above technical solution:

[0011] At least one thermistor is provided on the side and at both the top and bottom of the motor.

[0012] As a further description of the above technical solution:

[0013] The thermistor is attached to the motor.

[0014] As a further description of the above technical solution:

[0015] A handle is provided on one side of the vacuum cleaner body, and a battery pack is provided at the bottom of the handle.

[0016] As a further description of the above technical solution:

[0017] The main control board is located inside the battery pack.

[0018] As a further description of the above technical solution:

[0019] The main control board is located inside the handle.

[0020] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are as follows: by installing a thermistor on the motor, the thermistor collects the temperature data of the motor, the main control board processes the received temperature data, and when the motor reaches the set temperature, the motor stops working, effectively solving the problem of the motor overheating and causing machine damage when the suction port is blocked during the use of the vacuum cleaner.

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figs. 1-2This utility model provides a technical solution: a vacuum cleaner that avoids high-temperature operation of the motor, comprising:

[0028] Vacuum cleaner body 1, wherein a motor 2 is installed inside the vacuum cleaner body 1;

[0029] At least one thermistor 3 is disposed on the motor 2;

[0030] The main control board 4 is located inside the vacuum cleaner body 1, and the motor 2 and the thermistor 3 are both connected to the main control board 4.

[0031] The main control board 4 includes a CPU module, which processes the temperature data collected by the thermistor 3 and controls the start and stop of the motor 2 based on the processing results. The thermistor is used to collect the temperature of the motor. If the collected temperature exceeds a preset temperature, the main control board controls the motor control switch to cut off the power.

[0032] At least one thermistor 3 is provided on the side and at both the top and bottom of the motor 2. This can improve the accuracy of motor temperature acquisition.

[0033] The thermistor 3 is attached to the motor 2. This facilitates the installation of the thermistor.

[0034] A handle 5 is provided on one side of the vacuum cleaner body 1, and a battery pack 6 is provided at the bottom of the handle 5.

[0035] In one embodiment, the main control board 4 is disposed within the battery pack 6.

[0036] In another embodiment, the main control board 4 is disposed within the handle 5.

[0037] Working principle: By installing a thermistor on the motor, the thermistor collects the motor's temperature data. The main control board processes the received temperature data, and when the motor reaches the set temperature, the motor stops working. This effectively solves the problem of the motor overheating and causing machine damage when the suction port is blocked during vacuum cleaner use.

[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
