It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other arbitrarily without conflict.

[0023] The head assembly of the heat pump water heater provided by the embodiments of the present application comprises: Figures 1 to 6 as shown, comprising: a housing 100, the peripheral wall of the housing 100 is provided with a first air port 110 and a mounting port 120, the first air port 110 and the mounting port 120 are sequentially arranged in the peripheral direction of the housing 100; a mounting seat with an insert port 211, the mounting seat is fixedly arranged at the mounting port 120, and the insert port 211 is located in the mounting port 120; and a filter screen, the filter screen is detachably inserted into the housing 100 from the insert port 211 and is opposite to the first air port 110.

[0024] The head assembly, the filter screen is mounted on the peripheral wall of the housing 100, and the user dismounts and mounts the filter screen at the side of the head assembly, and the operation for dismounting and mounting the filter screen is more convenient. The first air port is an air inlet.

[0025] In some examples, the mounting seat comprises: a mounting frame 210 with an insert port 211, the mounting frame 210 is arranged at the mounting port 120; and a mounting bracket 220, the mounting bracket 220 is located in the housing 100 and fixes the mounting frame 210 on the housing 100, so that the mounting frame 210 and the housing 100 are fixedly connected together.

[0026] In some embodiments, as shown in Figure 1 and Figure 6As shown, the mounting frame 210 has a first abutting portion 212 and a connecting portion 213, the connecting portion 213 is located in the mounting port 120, the port wall of the mounting port 120 away from the first air port 110 is a first port wall 121, the first abutting portion 212 abuts the side of the first port wall 121 facing the outside of the shell 100, the mounting bracket 220 has a second abutting portion 221 and a connecting matching portion 222, the second abutting portion 221 abuts the side of the first port wall 121 facing the inside of the shell 100, the connecting portion 213 and the connecting matching portion 222 are connected, realizing that one end of the mounting frame 210 away from the first air port 110 is fixed on the shell 100; in addition, the mounting frame 210 also has a second slot 214, the slot opening of the second slot 214 on the circumferential direction of the shell 100 faces the side where the first air port 110 is located, the port wall of the mounting port 120 close to the first air port 110 is a second port wall 122, the second port wall 122 on the circumferential direction of the shell 100 is inserted into the second slot 214, realizing that one end of the mounting frame 210 close to the first air port 110 is fixed on the shell 100; this scheme makes the mounting frame 210 firmly fixed at the mounting port 120 and will not fall off by itself at the mounting port 120. Among them, on the circumferential direction of the shell 100, the part of the mounting frame 210 where the connecting portion 213 is arranged (towards the side away from the first air port 110) abuts on the mounting bracket 220, and the second port wall 122 is inserted into the second slot 214, so that the mounting bracket 220 can prevent the mounting frame 210 from shaking along the circumferential direction of the shell 100 in the mounting port 120.

[0027] As shown in Figure 6 , the installation process of the mounting frame 210 and the mounting bracket 220 on the shell 100 is as follows: first, place the mounting frame 210 at the mounting port 120, so that the second port wall 122 is inserted into the second slot 214, then make the first abutting portion 212 of the mounting frame 210 abut the side of the first port wall 121 facing the outside of the shell 100, and then make the second abutting portion 221 of the mounting bracket 220 abut the side of the first port wall 121 facing the inside of the shell 100, at this time the connecting matching portion 222 of the mounting bracket 220 is opposite to the connecting portion 213 of the mounting frame 210, and then the connecting matching portion 222 and the connecting portion 213 are fixedly connected together.

[0028] In some embodiments, as shown in Figure 5 and Figure 6 , the connecting portion 213 is a threaded hole, the threaded hole extends into the shell 100 from the mounting port 120, the connecting matching portion 222 is a through hole, the through hole is located on the radial inner side of the threaded hole on the radial direction of the shell 100, and a screw is screwed into the threaded hole through the through hole, realizing that the mounting bracket 220 fixes one end of the mounting frame 210 away from the first air port 110 at the first port wall 121. Among them, the first abutting portion 212 is arranged as an abutting flange, and the second abutting portion 221 is arranged as an abutting table.

[0029] In some embodiments, as shown in Figure 6 The second abutting part 221 is provided with a first slot 223, and the slot of the first slot 223 is directed to the radial outer side of the shell 100. The first port wall 121 is provided with a plug 123 bent towards the inside of the shell 100. The plug 123 is inserted into the first slot 223 in the radial direction of the shell 100. The plug 123 can effectively improve the structural strength of the first port wall 121, so that the first port wall 121 is less likely to deform. Moreover, the plug 123 is inserted into the first slot 223, and the connecting part 222 is connected to the connecting part 213. This can prevent the mounting frame 210 and the mounting bracket 220 from shaking in the circumferential direction of the shell 100.

[0030] In some examples, as shown in Figures 1 to 4 , Figure 6 The filter screen includes a screen body 310 and a holding seat 320. The holding seat 320 is fixedly installed at one end of the screen body 310. The other end of the screen body 310 is inserted into the shell 100 from the plug 211. The screen body 310 is opposite to the first air port 110. The user can conveniently dismount and install the screen body 310 at the first air port 110 by grabbing the holding seat 320. This scheme makes the action of the user dismounting and installing the filter screen simpler.

[0031] In some embodiments, as shown in Figures 3 to 5 The holding seat 320 and the mounting frame 210 are provided with a buckle 410 and a buckle position 420, respectively. The buckle 410 and the buckle position 420 are detachably connected to each other. This can detachably fix the holding seat 320 in the plug 211. Moreover, this scheme can also better ensure that the screen body 310 is completely opposite to the first air port 110 after being installed in place.

[0032] In some embodiments, as shown in Figure 2 and Figure 6 The holding seat 320 is provided with a hand holding slot 321. The slot of the hand holding slot 321 is directed to the outside of the shell 100. The user can conveniently insert and pull out the holding seat 320 at the plug 211 by grabbing the hand holding slot. This makes the action of the user dismounting and installing the filter screen simpler.

[0033] In some embodiments, as shown in Figure 1 In the circumferential direction of the shell 100, the two sides of the first air port 110 are provided with mounting ports 120, mounting frames 210, mounting brackets 220, and filter screens. One part of the first air port 110 is opposite to the screen body 310 of one filter screen. Another part of the first air port 110 is opposite to the screen body 310 of another filter screen.
