[0023] To make the above-mentioned objects, features, and advantages of the present invention more clearly understood, the following detailed description of specific embodiments of the present invention is provided in conjunction with the accompanying drawings. The following description sets forth many specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0024] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may also be an element centered thereon. When an element is considered to be "connected" to another element, it may be directly connected to the other element or there may also be an element centered thereon. When the number of an element is referred to as having "plurality", it may be any number of two or more. The terms "vertical", "horizontal", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation method.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as those commonly understood by those skilled in the art to which this invention pertains. The terms used herein in the specification of this invention are intended solely for the purpose of describing specific embodiments and are not intended to limit this invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0026] The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings:

[0027] like Figure 1-4 As shown, in this embodiment, a pillow with a mortise and tenon structure is provided, comprising an upper pillow block and a lower pillow block. The bottom surface of the upper pillow block and the top surface of the lower pillow block are each provided with an assembly structure. Specifically, the bottom surface of the upper pillow block and the top surface of the lower pillow block are each provided with a matching male and female assembly structure. One half of the upper pillow block is thicker than the other half. Specifically, a recessed area is provided at the center of the top of the upper pillow block. Specifically, a downwardly recessed centerline is provided at the top of the upper pillow block. Pillow slopes of varying heights are arranged on either side of the recessed area. The centerline divides the two sides of the upper pillow block into two pillow slopes of varying heights (thicknesses). The centerline, or recessed area, stabilizes the user's head position.

[0028] By the same token, the thickness of half of the lower pillow block is greater than the thickness of the other half, but in order to ensure that the pillow can be placed horizontally on the bed surface, the bottom of the lower pillow block is horizontal.

[0029] In summary, the present invention provides different assembly structures to suit different users' sleep qualities and habits, based on the corresponding assembly surfaces of the upper and lower pillow blocks. This minimizes the chance of the upper and lower pillow blocks becoming detached during sleep. Furthermore, even when detached, they can be quickly and easily reassembled. The following are several embodiments. The remaining structures remain the same, so only the differences are highlighted. Example 1:

[0030] The bottom of the upper pillow block is provided with a wavy male surface for assembly, and the bottom of the lower pillow block is provided with a corresponding wavy female surface for assembly. In other words, the upper pillow block is provided with regular raised strips and recessed grooves, and the lower pillow block is also provided with regular raised strips and recessed grooves to match the upper pillow block. Figure 2 and Figure 5 As shown in the figure, depending on the assembly relationship, the pillow edge used by the user (the pillow edge refers to the halfway point from one side of the pillow to the middle of the pillow) can be seen. The height of the upper pillow block is a + b, while the height of the lower pillow block is a + b. Therefore, the height combinations of the pillow edge after assembly include a + b, b + b, and a + a. Example 2:

[0031] To further explain, a tooth-shaped assembly male surface is provided at the bottom of the upper pillow block, and a corresponding tooth-shaped assembly female surface is provided at the bottom of the lower pillow block. The tooth-shaped assembly male surface and the tooth-shaped assembly female surface are respectively provided with teeth and recessed tooth root recesses, which will engage with each other during assembly. Example 3:

[0032] To further elaborate, the bottom of the upper pillow block is provided with a downwardly extending protruding assembly male surface, and the bottom of the lower pillow block is provided with a correspondingly recessed assembly female surface. During assembly, the protruding assembly male surface will be inserted into the assembly female surface.

[0033] The assembly closing surfaces of all the above-mentioned embodiments are inclined. Specifically, the assembly female surface at the top of the lower pillow block is inclined, and the assembly male surface at the bottom of the upper pillow block is also inclined corresponding to the assembly female surface.

[0034] The technical features of the above-described embodiments can be combined in any manner. To simplify the description, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there are no contradictions in the combination of these technical features, they should be considered to be within the scope of this specification. For those skilled in the art, without departing from the concept of the utility model, they can also make several variations and improvements, which fall within the scope of protection of the utility model. Therefore, the scope of protection of this utility model patent shall be based on the appended claims.
