[0027] To make the technical solution of the present utility model clearer, the following further describes the present utility model in detail with reference to the accompanying drawings and specific embodiments.

[0028] Embodiment 1

[0029] Combined with the attached Figures 1-9 A water pump with a quickly replaceable pump head is assembled from a motor main body 10 and a pump head 11. The pump head 11 can be quickly installed on the motor main body 10 and can be quickly removed from the motor main body 10 when the pump head 11 needs to be replaced. The motor main body 10 is the power end that provides power for the operation of the pump head 11. The pump head 11 is a functional component. In actual use, there is no need to be limited to the pump head of a water pump. It is also possible to use a functional component with other functions to replace the pump head and install it on the motor main body 10.

[0030] The interior of the motor main body 10 has a conventional structure of a motor, which consists of a power supply part, a stator, an output shaft, and a rotor installed on the output shaft. The cooperation between the stator and the rotor drives the output shaft to rotate. Any type of motor can be quickly connected and disassembled with the functional component by simply modifying the output.

[0031] At the same time, other power components with output shafts can also use the structure of this technical solution, such as an engine as an example.

[0032] An output shaft 12 is provided inside the motor main body 10. At the end of the output shaft 12 facing the pump head 11, there is a power bevel gear 13. The power bevel gear 13 consists of a power bevel gear rotating wheel 131 and a power bevel gear mating tooth 132. The power bevel gear rotating wheel 131 of the power bevel gear 13 is used to be fixedly connected to the output shaft 12. When the motor main body 10 is powered on to make the output shaft 12 rotate, the output shaft 12 drives the power bevel gear rotating wheel 131 to rotate.

[0033] The power bevel gear mating tooth 132 is formed by a plurality of individual mating teeth evenly arranged around the side of the power bevel gear rotating wheel 131 facing the pump head 11. The power bevel gear mating tooth 132 is arranged around the center on the side of the power bevel gear rotating wheel 131.

[0034] When the driving bevel gear rotating wheel 131 rotates, it drives the driving bevel gear mating tooth 132 thereon to rotate, thereby further transmitting power. The driving bevel gear mating tooth 132 is a deflecting bevel tooth with an inclined surface. The orientation of the inclined surface of the driving bevel gear mating tooth 132 is consistent with the rotation direction of the driving bevel gear rotating wheel 131. The deflecting tooth of the driving bevel gear mating tooth 132 is formed by extending from the tooth width of the driving bevel gear mating tooth 132 on the side of the driving bevel gear rotating wheel 131 towards the pump head 11 and gradually narrowing.

[0035] The pump head 11 is composed of a conventional water inlet channel, a water outlet channel, blades for driving water flow, and a driven shaft 14 connected to the blades. The conventional water inlet channel, the water outlet channel, and the blades for driving water flow can be changed according to the usage requirements of the pump head. A driven bevel gear 15 is provided on the output shaft 14 for driving various forms of blades. The driven bevel gear 15 is used to cooperate with the driving bevel gear 13. Thus, when the output shaft 12 outputs power to drive the driving bevel gear 13 to rotate, it can drive the driven bevel gear 15 to rotate, thereby further driving the blades to rotate and making the pump head 11 start to work.

[0036] The driven bevel gear 15 is also composed of a driven bevel gear rotating wheel 152 and a driven bevel gear mating tooth 152. The driven bevel gear mating tooth 152 is formed by evenly surrounding a plurality of individual mating teeth on the side of the driven bevel gear rotating wheel 152 facing the motor body 10. The driven bevel gear rotating wheel 152 is centrally surrounded on the side of the driven bevel gear mating tooth 152.

[0037] The driven bevel gear mating tooth 152 is a deflecting bevel tooth with an inclined surface. The orientation of the inclined surface of the driven bevel gear mating tooth 152 is consistent with the rotation direction of the driven bevel gear rotating wheel 152. The deflecting tooth of the driving bevel gear mating tooth 132 is formed by extending from the tooth width of the driving bevel gear mating tooth 132 on the side of the driving bevel gear rotating wheel 131 towards the motor body 10 and gradually narrowing.

[0038] The number and installation positions of the deflecting bevel teeth of the driving bevel gear mating tooth 132 and the driven bevel gear mating tooth 152 are correspondingly set. And since both the driving bevel gear mating tooth 132 and the driven bevel gear mating tooth 152 are inclined surfaces, the driving bevel gear 13 and the driven bevel gear 15 will not get stuck when combined. Even if the driving bevel gear 13 and the driven bevel gear 15 do not contact during assembly, after the driving bevel gear 13 rotates, it can abut against the driven bevel gear 15 and drive it to rotate.

[0039] When the motor main body 10 and the pump head 11 are combined for transmission work, the power bevel gear 13 and the driven bevel gear 15 transmit power through abutment. At this time, the deflection inclined surfaces of the mating teeth 132 of the power bevel gear and the deflection inclined surfaces of the mating teeth 152 of the driven bevel gear abut to form a deflection inclined surface. Through the tooth crest of the mating tooth 132 of the power bevel gear and the tooth root of the mating tooth 152 of the driven bevel gear being located at the same position, and the tooth root of the mating tooth 132 of the power bevel gear and the tooth crest of the mating tooth 152 of the driven bevel gear being located at the same position, the full cooperation of the mating tooth 132 of the power bevel gear and the mating tooth 152 of the driven bevel gear is achieved by means of insertion, so as to drive the driven bevel gear 15 to rotate when the power bevel gear 13 rotates.

[0040] A mating structure for cooperating with the pump head 11 is provided on the side of the motor main body 10. A mating space 16 is provided inside the mating structure of the motor main body 10. A connecting structure 17 for inserting into the mating space 16 is provided on the pump head 11. The mating structure of the motor main body 10 is a hollow structure with a mating space 16. The connecting structure 17 of the pump head 11 is correspondingly arranged with the mating structure of the motor main body 10 with the mating space 16. After the connecting structure 17 of the pump head 11 is inserted into the mating space 16 of the mating structure of the motor main body 10, the pump head 11 and the motor main body 10 can be in full contact, so that when the power bevel gear 13 and the driven bevel gear 15 are engaged in transmission, the synchronism can be improved and the oscillation and shaking can be reduced.

[0041] A connecting card slot 18 is provided in the mating space 16 of the mating structure of the motor main body 10. A snap 19 is slidably provided in the connecting card slot 18. A circular through hole 20 is provided in the snap 19. An elastic member 21 is provided between the snap 19 and the bottom of the connecting card slot 18. The elastic member 21 is preferably a spring.

[0042] A protrusion needs to be provided on the top of the snap 19 for the user to press, so that the snap 19 slides in the card slot 18.

[0043] An annular groove 22 is provided on the connecting structure 17 of the pump head 11. The annular groove 22 is correspondingly arranged with the snap 19. After the connecting structure 17 of the pump head 11 is inserted into the circular through hole 20 of the snap 19, the snap 19 can be snapped into the annular groove 22. When the snap 19 slides down in the card slot 18, the circular through hole 20 of the snap 19 can allow the connecting structure 17 of the pump head 11 to be inserted.

[0044] The snap 19 can fix the pump head 11 in the motor main body 10, and the snap 19 can also be used as a component to indicate whether the installation position of the pump head 11 is correct. After the pump head 11 is inserted into the correct position of the motor main body 10, the elastic member 21 will push the snap 19 into the annular groove 22, thus making a sound to assist the user in determining that the pump head 11 is installed in place.

[0045] In use, the user first presses the protrusion on the top of the buckle 19, so that the buckle 19 slides down in the card slot 18. At this time, the circular through-hole 20 of the buckle can allow the pump head 11 to be inserted. The user inserts the connection structure 17 of the pump head 11 into the fitting space 16 until the annular groove 22 of the connection structure 17 of the pump head 11 reaches the position of the buckle 19. At this time, the rising part of the buckle 19 is inserted into the annular groove 22. At this time, the pump head 11 and the motor main body 10 are fixed. The user then performs a threaded connection on the pump head 11 and the motor main body 10 to strengthen the connection between the pump head 11 and the motor main body 10. At this time, the driving bevel gear 13 and the driven bevel gear 15 reach the correct fitting position, and the driving bevel gear 13 can drive the driven bevel gear 15.

[0046] The above-described embodiments merely represent several implementation manners of the present invention. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the patent of the present invention should be subject to the appended claims.
