The technical solution of the present invention will be further described with reference to the following embodiments and the accompanying drawings.

Referring to fig. 1 to 4, an embodiment of the present invention discloses a tooth rinsing device host 100, where the tooth rinsing device host 100 includes a host casing 1, a first guide 111, a movement assembly 2, and a second guide 21, the host casing 1 is provided with an installation cavity 11, the first guide 111 is provided on a wall surface of the installation cavity 11, the second guide 21 is provided on the movement assembly 2, the movement assembly 2 can be slidably connected with the first guide 111 through the second guide 21 to be installed in the installation cavity 11, wherein at least one of the first guide 111 and the second guide 21 is an elastic member, and when the first guide 111 is connected with the second guide 21 in a matching manner, the first guide 111 and the second guide 21 abut against each other, so that the movement assembly 2 is elastically matched in the installation cavity 11 in a tight manner, and the elastic matching is used for reducing vibration transmission between the movement assembly 2 and the host casing 1.

When installing the core assembly 2, the core assembly 2 can be installed in the installation cavity 11 of the main machine housing 1 under the guiding action of the first guide 111 and the second guide 21, and since at least one of the first guide 111 and the second guide 21 is an elastic member, during the installation of the core assembly 2 in the installation cavity 11 of the main machine housing 1, at least one of the first guide 111 and the second guide 21 can be adapted to be deformed so that the first guide 111 and the second guide 21 can be tightly abutted against each other, thereby enabling a zero-fit or an interference fit to be formed between the first guide 111 and the second guide 21 so as to tightly install the core assembly 2 in the installation cavity 11 of the main machine housing 1. Thus, the first guide 111 and the second guide 21 can be used to elastically assemble the movement assembly 2 and the main housing 1, and the number of assembling parts for assembling the movement assembly 2 and the main housing 1 can be reduced, so that the assembling efficiency of the movement assembly 2 can be improved, and the assembly for reducing the vibration transmission can be formed.

In addition, when the core assembly 2 works, at least one of the first guide 111 and the second guide 21 is an elastic member, which can provide a damping function, and reduce the vibration caused by the work of the motor and the pump body in the core assembly 2 from being transmitted to the main machine housing 1, thereby being beneficial to reducing and buffering the noise generated when the dental appliance main machine 100 works.

Further, since at least one of the first guide 111 and the second guide 21 is an elastic member, the assembly between the movement assembly 2 and the main machine housing 1 is soft, and compared with the way that the assembly between the movement assembly 2 and the main machine housing 1 is hard, the assembly precision between the movement assembly 2 and the main machine housing 1 is lower, so that the tolerance of the mold opening error of the movement housing 22 of the main machine housing 1 and the movement assembly 2 is higher.

In the present embodiment, at least one of the first guide 111 and the second guide 21 being an elastic member can be understood as: only the first guide member 111 may be an elastic member, such as a silicone member, a foam member, a plastic member, or a rubber member, or only the second guide member 21 may be an elastic member, such as a silicone member, a foam member, a plastic member, or a rubber member, or both the first guide member 111 and the second guide member 21 may be elastic members, such as a silicone member, a foam member, a plastic member, or a rubber member.

Since the assembly between the movement assembly 2 and the main housing 1 is a soft assembly, in order to form a stable assembly relationship between the movement assembly 2 and the main housing 1, in some embodiments, the first guide 111 may be a plurality of, for example, two, three, four or more, the plurality of first guides 111 may be arranged at intervals, the plurality of second guides 21 may also be a plurality of, for example, two, three, four or more, the plurality of second guides 21 are arranged in one-to-one correspondence with the plurality of first guides 111 and are in fit connection with the corresponding first guides 111, when each first guide 111 is in fit connection with the corresponding second guide 21, each first guide 111 and the corresponding second guide 21 abut against each other, so that the movement assembly 2 is tightly and elastically fitted in the mounting cavity 11, so that a connection area between the movement assembly 2 and the main housing 1 can be increased, and thus connection stability between the movement assembly 2 and the main housing 1 can be improved.

Further, a plurality of first guides 111 can be evenly set up in host computer casing 1 at the interval, and a plurality of second guides 21 also can be evenly set up on core subassembly 2 at the interval, can form more stable assembly structure between core subassembly 2 and host computer casing 1 like this to make and form more stable assembly relation between core subassembly 2 and the host computer casing 1, thereby be favorable to further improving the connection stability between core subassembly 2 and the host computer casing 1. Exemplarily, in the embodiment shown in fig. 2 and 4, the main body housing 1 is provided with two opposite first guide pieces 111 in the left-right direction, while the deck assembly 2 is provided with two opposite second guide pieces 21 in the left-right direction, the two first guide pieces 111 and the corresponding first guide pieces 111 are in fit connection, and when the two first guide pieces 111 and the corresponding second guide pieces 21 are in fit connection, the two first guide pieces 111 and the corresponding second guide pieces 21 abut against each other, so that the deck assembly 2 is tightly fitted in the mounting cavity 11.

It is to be noted that, in order to facilitate the installation of the movement assembly 2 into the installation cavity 11 of the main body housing 1, the installation cavity 11 has an inlet 112, the first guide member 111 may be arranged to extend from the inlet 112 of the installation cavity 11, the movement assembly 2 may be installed into the installation cavity 11 of the main body housing 1 from the inlet 112 of the installation cavity 11 along the extending direction of the first guide member 111, and the sliding installation direction of the movement assembly 2 is the extending direction of the first guide member 111, for example, the front-back direction in fig. 2.
